v0.4.0

Compare Source

Removed

• The Criterion::can_plot function has been removed.
• The Criterion::bench_function_over_inputs function has been removed.
• The Criterion::bench_functions function has been removed.
• The Criterion::bench function has been removed.

Changed

• HTML report hidden behind non-default feature flag: 'html_reports'
• Standalone support (ie without cargo-criterion) feature flag: 'cargo_bench_support'
• MSRV bumped to 1.57
• rayon and plotters are optional (and default) dependencies.
• Status messages ('warming up', 'analyzing', etc) are printed to stderr, benchmark results are printed to stdout.
• Accept subsecond durations for --warm-up-time, --measurement-time and --profile-time.
• Replaced serde_cbor with ciborium because the former is no longer maintained.
• Upgrade clap to v3 and regex to v1.5.

Added

• A --discard-baseline flag for discarding rather than saving benchmark results.
• Formal support for benchmarking code compiled to web-assembly.
• A --quiet flag for printing just a single line per benchmark.
• A Throughput::BytesDecimal option for measuring throughput in bytes but printing them using decimal units like kilobytes instead of binary units like kibibytes.

Fixed

• When using bench_with_input, the input parameter will now be passed through black_box before passing it to the benchmark.

v0.3.6

Compare Source

Changed

• MSRV bumped to 1.49
• Symbol for microseconds changed from ASCII 'us' to unicode 'µs'
• Documentation fixes
• Clippy fixes

v0.3.5

Compare Source

Fixed

• Corrected Criterion.toml in the book.
• Corrected configuration typo in the book.

Changed

• Bump plotters dependency to always include a bug-fix.
• MSRV bumped to 1.46.

v0.3.4

Compare Source

Added

• Added support for benchmarking async functions
• Added with_output_color for enabling or disabling CLI output coloring programmatically.

Fixed

• Criterion.rs will now give a clear error message in case of benchmarks that take zero time.
• Added some extra code to ensure that every sample has at least one iteration.
• Added a notice to the --help output regarding "unrecognized option" errors.
• Increased opacity on violin charts.
• Fixed violin chart X axis not starting at zero in the plotters backend.
• Criterion.rs will now automatically detect the right output directory.

Deprecated

• Criterion::can_plot is no longer useful and is deprecated pending deletion in 0.4.0.
• Benchmark and ParameterizedBenchmark were already hidden from documentation, but are now formally deprecated pending deletion in 0.4.0. Callers should use BenchmarkGroup instead.
• Criterion::bench_function_over_inputs, Criterion::bench_functions, and Criterion::bench were already hidden from documentation, but are now formally deprecated pending deletion in 0.4.0. Callers should use BenchmarkGroup instead.
• Three new optional features have been added; "html_reports", "csv_output" and "cargo_bench_support". These features currently do nothing except disable a warning message at runtime, but in version 0.4.0 they will be used to enable HTML report generation, CSV file generation, and the ability to run in cargo-bench (as opposed to cargo-criterion). "cargo_bench_support" is enabled by default, but "html_reports" and "csv_output" are not. If you use Criterion.rs' HTML reports, it is recommended to switch to cargo-criterion. If you use CSV output, it is recommended to switch to cargo-criterion and use the --message-format=json option for machine-readable output instead. A warning message will be printed at the start of benchmark runs which do not have "html_reports" or "cargo_bench_support" enabled, but because CSV output is not widely used it has no warning.

v0.3.3

Compare Source

Added

• Added CRITERION_HOME environment variable to set the directory for Criterion to store its results and charts in.
• Added support for [cargo-criterion]. The long-term goal here is to remove code from Criterion-rs itself to improve compile times, as well as to add features to cargo-criterion that are difficult to implement in Criterion-rs.
• Add sampling mode option for benchmarks. This allows the user to change how Criterion.rs chooses the iteration counts in each sample. By default, nothing will change for most benchmarks, but very slow benchmarks will now run fewer iterations to fit in the desired number of samples. This affects the statistics and plots generated.

Changed

• The serialization format for some of the files has changed. This may cause your first benchmark run after updating to produce errors, but they're harmless and will go away after running the benchmarks once.

Fixed

• Fixed a bug where the current measurement was not shown on the relative regression plot.
• Fixed rare panic in the plotters backend.
• Panic with a clear error message (rather than panicking messily later on) when the user sets the group or function name to the empty string.
• Escape single quotes in benchmark names when generating Gnuplot scripts.

v0.3.2

Compare Source

Added

• Added ?Sized bound to benchmark parameter types, which allows dynamically sized types like &str and &[T] to be used as benchmark parameters.
• Added the --output-format <format> command-line option. If --output-format bencher is passed, Criterion.rs will print its measurements in a format similar to that used by the bencher crate or unstable libtest benchmarks, and using similar statistical measurements as well. Though this provides less information than the default format, it may be useful for supporting tools which parse this output format.
• Added --nocapture argument. This argument does nothing, but prevents Criterion.rs from exiting when running tests or benchmarks and allowing stdout output from other tests.

Fixed

• Fixed panic when environment variables contains non-UTF8 characters.
• Fixed panic when CRITERION_DEBUG or CRITERION_TARGET_DIR environment variables contain non-UTF8 characters.

v0.3.1

Compare Source

Added

• Added new plotting backend using the plotters crate. Implementation generously provided by Hao Hou, author of the plotters crate.
• Added --plotting-backend command-line option to select the plotting backend. The existing gnuplot backend will be used by default when available, and the plotters backend will be used when gnuplot is not available or when requested.
• Added Criterion::plotting_backend() function to configure the plotting backend in code.
• Added --load-baseline command-line option to load a baseline for comparison rather than measuring the current code
• Benchmark filters can now be regular expressions.

Fixed

• Fixed fibonacci functions.
• Fixed #[criterion] benchmarks ignoring the command-line options.
• Fixed incorrect scaling of the violin plots.
• Don't print the recommended sample count if it's the same as the configured sample count.
• Fix potential panic when nresamples is set too low. Also added a warning against setting nresamples too low.
• Fixed issue where a slow outer closure would cause Criterion.rs to calculate the wrong estimated time and number of iterations in the warm-up phase.

v0.8.1

Compare Source

• Add "caching" and "no-std" to list of categories.

v0.8.0

Compare Source

• Use NonZeroUsize for LRU capacity instead of usize.
• Add get_or_insert_mut method which is similiar to get_or_insert but returns a mutable reference instead of an immutable reference.
• Add LruCache::promote and LruCache::demote API to manipulate LRU order of the entry directly.

v0.11.0

Compare Source

PROST! is a Protocol Buffers implementation for the Rust Language. prost generates simple, idiomatic Rust code from proto2 and proto3 files.

Relase 0.11 brings a few breaking changes and changes to how prost sources protoc.

• prost-build now requires protoc to be available in the path or set via the PROTOC env var.
• prost-types now contains new Timestamp/Duration FromStr implementations.
• MSRV bump to 1.56 and all crates have been moved to edition 2021

Notible changes that are not breaking:

• prost-build now has a cleanup-markdown feature for cleaining up code blocks from protobuf files so that they work under rustdoc tests.
• prost-build now generates as_str_name for message types.

v0.9.0

Compare Source

API documentation: https://docs.rs/serde_yaml/0.9

Highlights

• The serde_yaml::Value enum gains a Tagged variant which represents the deserialization of YAML's !Tag syntax. Tagged scalars, sequences, and mappings are all supported.

• An empty YAML input (or document containing only comments) will deserialize successfully to an empty map, empty sequence, or Serde struct as long as the struct has only optional fields. Previously this would error.

• A new .apply_merge() method on Value implements YAML's << merge key convention.

• The Debug representation of serde_yaml::Value has gotten vastly better (https://github.com/dtolnay/serde-yaml/pull/287).

• Deserialization of borrowed strings now works.

  #[derive(Deserialize, Debug)]
  struct Struct<'a> {
      borrowed: &'a str,
  }
  
  let yaml = "borrowed: 'kölcsönzött'\n";
  let value: Struct = serde_yaml::from_str(yaml)?;
  println!("{:#?}", value);
  

• Value's and Mapping's methods get and get_mut have been generalized to support a &str argument, as opposed to requiring you to allocate and construct a Value::String for indexing into another existing Value.

• Mapping exposes more APIs that have become conventional on map data structures, such as .keys(), .values(), .into_keys(), .into_values(), .values_mut(), and .retain(|k, v| …).

Breaking changes

• Serialization no longer produces leading ---\n on the serialized output. You can prepend this yourself if your use case demands it.

• Serialization of enum variants is now based on YAML's !Tag syntax, rather than JSON-style singleton maps.

  #[derive(Serialize, Deserialize)]
  enum Enum {
      Newtype(usize),
      Tuple(usize, usize, usize),
      Struct { x: f64, y: f64 },
  }
  

  - !Newtype 1
  - !Tuple [0, 0, 0]
  - !Struct {x: 1.0, y: 2.0}
  

• A bunch of non-base-10 edge cases in number parsing have been resolved. For example 0x+1 and ++0x1 are now parsed as strings, whereas they used to be incorrectly treated as numbers.

• Deserializers obtained through iteration can no longer be iterated further:

  let deserializer = serde_yaml::Deserializer::from_str(multiple_documents);
  for de in deserializer {
      // correct:
      let myvalue = T::deserialize(de)?;
  
      // incorrect: used to produce some questionable result, now produces 0 sub-documents
      for questionable in de {
          let wat = T::deserialize(questionable)?;
      }
  }
  

• The abandoned yaml-rust crate is no longer used as the YAML backend. The new libyaml-based backend surely has different edge cases and quirks than yaml-rust.

• Some excessive PartialEq impls have been eliminated.

• The serde_yaml::to_vec function has been removed. Use serde_yaml::to_writer for doing I/O, or use serde_yaml::to_string + .into_bytes() on the resulting String.

• The serde_yaml::seed module has been removed. Now that a serde_yaml::Deserializer is publicly available, the same use cases can be addressed via seed.deserialize(Deserializer::from_str(…)) instead.

Bugfixes

• Empty values in a mapping are supported, and deserialize to empty string when the corresponding struct field is of type string. Previously they would deserialize to "~" which makes no sense.

• 128-bit integer deserialization now supports hex and octal input.

• Serde_yaml now includes a mitigation against a "billion laughs" attack in which malicious input involving YAML anchors and aliases is used to consume an amount of processing or memory that is exponential in the size of the input document. Serde_yaml will quickly produce an error in this situation instead.
