Keeping Track Of Issues And Prs

Keeping track of issues and PRs

The Tokio GitHub repository has a lot of issues and PRs to keep track of. This section explains the meaning of various labels, as well as our GitHub project. The section is primarily targeted at maintainers. Most contributors aren't able to set these labels.

Area

The area label describes the crates relevant to this issue or PR.

• A-ci This issue concerns our GitHub Actions setup.
• A-tokio This issue concerns the main Tokio crate.
• A-readme This issue is related to documentation such as README.md.
• A-benches This issue concerns the benchmarks.
• A-examples This issue concerns the examples.
• A-tokio-test The issue concerns the tokio-test crate.
• A-tokio-util This issue concerns the tokio-util crate.
• A-tokio-macros This issue concerns the tokio-macros crate. Should only be used for the procedural macros, and not join! or select!.
• A-tokio-stream This issue concerns the tokio-stream crate.

Category

• C-bug This is a bug-report. Bug-fix PRs use C-enhancement instead.
• C-enhancement This is a PR that adds a new features.
• C-maintenance This is an issue or PR about stuff such as documentation, GitHub Actions or code quality.
• C-feature-request This is a feature request. Implementations of feature requests use C-enhancement instead.
• C-feature-accepted If you submit a PR for this feature request, we won't close it with the reason "we don't want this". Issues with this label should also have the C-feature-request label.
• C-musing Stuff like tracking issues or roadmaps. "musings about a better world"
• C-proposal A proposal of some kind, and a request for comments.
• C-question A user question. Large overlap with GitHub discussions.
• C-request A non-feature request, e.g. "please add deprecation notices to -alpha.* versions of crates"

Calls for participation

• E-help-wanted Stuff where we want help. Often seen together with C-bug or C-feature-accepted.
• E-easy This is easy, ranging from quick documentation fixes to stuff you can do after reading the tutorial on our website.
• E-medium This is not E-easy or E-hard.
• E-hard This either involves very tricky code, is something we don't know how to solve, or is challenging for some other reason.
• E-needs-mvce This bug is missing a minimal complete and verifiable example.

The "E-" prefix is the same as used in the Rust compiler repository. Some issues are missing a difficulty rating, but feel free to ask on our Discord server if you want to know how challenging an issue likely is.
