Override workspace.lints

help

Hello,

I wish to override the workspace.lints from the workspace in sub crates.

I found this.

Is there a workaround ?

Thank you very much in advance for any help

There is no cargo-level way to do it yet. [lints] workspace = true is all or nothing — if you add any key next to it in the package you get

cannot override `workspace.lints` in `lints`, either remove the overrides or `lints.workspace = true` and manually specify the lints

This is by design — RFC 3389 says "it is a hard error to mix workspace = true and lints" (3389-manifest-lint - The Rust RFC Book).

Two workarounds that work today (checked on 1.98 on my machine):

  1. Put the override in the crate root instead of Cargo.toml: #![allow(some_lint)] or #![warn(...)] at the top of lib.rs / main.rs. Cargo passes workspace lints to rustc as -A/-W/-D flags, and source attributes take precedence over command-line flags, so a workspace deny can be relaxed to allow in that one crate this way.

  2. Drop workspace = true in that crate and write its full [lints.rust] / [lints.clippy] table by hand. Then the workspace table is ignored entirely for that package, so you have to restate everything you still want.

1 is less duplication. 2 is better if the crate really wants a different policy. priority doesn't help here, it only orders lints within a single table.

Please don't post machine-generated text verbatim here on URLO. It is against the ToS.
