We may want to have one nightly build that runs clippy over our code. Clippy gets new and improved lints all the time, so having it run could be useful.

Question: Current Working Directory for iai benchmarks?

Hi there! I have an operation I want to benchmark which accesses a directory within the environment. What is the current working directory the benchmarks are run in? Also I...

Anti-Pattern: Intermediate `collect()`ion

7

I sometimes see this in code from iterative-minded folks, they iterate over something, collecting the result in a `Vec`. Then they iterate over the `Vec`, producing yet another `Vec`. In...

Lazy allocation (in collection types)

2

If you create a collection type, avoid allocating until the first element is inserted. This has the nice property of being able to avoid allocation altogether if the collection stays...

Matches: `skip_bytes` or `skip_until` method

3

If I want to ignore matches in a certain region of my text, I currently need to loop until `.next()` returns `None` or the `.start()` of the returned `Match` is...

lint Arc<_> within non Send/Sync type

4

`Arc` only implements `Send`+`Sync` for contained types that are themselves `Send` and `Sync`. So wrapping a non-`Send`/`Sync` type in an Arc won't make it shareable. Using a `Rc` instead could...

Feature request: Quick fix: Create Method

2

This is something that works in JDT and CDT, and as Rust uses local type inference, it's a massively useful feature. If you don't know how it works, let's suppose...

Suggested extension: Check printf pattern in org.apache.logging.log4j.Logger.printf(Level, message, ...)

3

This is for Log4J2 – `System.out.printf("%d", 3.1415)` gets a warning, whereas `log.printf(Level.INFO, "%d", 3.1415)` is not detected.

Document mutations

We should have some document that outlines which mutations are actually there and what they do to the code.
