Minimalist YAML parser with support for borrowed string slices

31

In https://github.com/dtolnay/serde-yaml/issues/94 I would like to move serde-yaml off of [yaml-rust](https://github.com/chyh1990/yaml-rust) as a YAML backend and to a much simpler backend with support for a minimum viable subset of YAML...

A dtd macro to generate struct definitions from an XML DTD file

I would like to be able to write: ```rust dtd!("path/to/note.dtd"); ``` or possibly inline: ```rust dtd! { } ``` and have this expand to the right data structures to represent...

Attribute macro to generate de/serialization functions for fields of big array type

Like all of the standard library's traits, Serde's traits are limited to fixed size arrays up to an arbitrary maximum size. Serde defines Serialize and Deserialize impls for arrays up...

Serde format for in situ JSON deserialization

Originally filed as https://github.com/serde-rs/json/issues/318, but since this will involve quite a bit more unsafe code than currently exists in serde_json I think it could be better to put in a...

Cargo subcommand to perform pluggable expansions against rustdoc

In the GitBook that backs https://serde.rs, I use [several GitBook plugins](https://github.com/serde-rs/serde-rs.github.io/blob/67d32d8af27e27f367438e25dc90dde6be10a660/book.json#L5), a few of which I wrote myself. For example I have a plugin that lets me insert playground links...

Originally requested in https://github.com/dtolnay/miniserde/issues/3 but Miniserde is taking a minimal approach that does not leave room for shipping helpers like that in-crate. The Display and FromStr adapters in that thread...

Support string literal patterns

1

This currently doesn't work, because I think we are looking for idents/paths only. We should add support for literals. ```rust #[remain::check] fn former_lint_group(lint_id: &str) -> Option { #[sorted] match lint_id...

Some ICEs manifest as if the crate compiled successfully

2

For example the following ICE in nightly-2020-06-04 (https://github.com/rust-lang/rust/issues/97698): ```rust // tests/compiletest.rs #[test] fn ui() { let t = trybuild::TestCases::new(); t.compile_fail("tests/ui/break-rust.rs"); } ``` ```rust // tests/ui/break-rust.rs trait AmbiguousIfImpl { fn method()...

Consider how to replace CARGO_MANIFEST_DIR without trailing slash

https://github.com/dtolnay/trybuild/issues/202#issuecomment-1284634512 > My macro outputs "Help: Searching in directory $CARGO_MANIFEST_DIR" when the file it was looking for doesn't exist, which by its nature, will not always be the same path....

```console test tests/ui/error.rs ... error Expected test case to fail to compile, but it succeeded. ``` Even though, compiling the same macro invocation directly using cargo, cargo sees that it...
