Configuring clippy in Cargo.toml missing from documentation?

[szabgab]

Description

I don't know where did I see that Clippy can be configured in Cargo.toml, but I don't seem to find it anywhere in the documentation. I also searched for the word priority and it was only mentioned in the prioritization of tasks not related to how the lints are prioritized.

• uninlined_format_args cannot be "allowed" in Cargo.toml #12161
• Can't disable new struct_field_names lint #12093
• See RFC 3389
• the lints section of Cargo.toml

I just tried to get this lint configured

multiple_crate_versions = { level = "warn", allowed-duplicate-crates = [
  "async-lock",
] }

Which results in

warning: /home/myself/source/my_app/Cargo.toml: unused manifest key: workspace.lints.clippy.multiple_crate_versions.allowed-duplicate-crates
    Checking my_package_1 v0.1.0 (/home/myself/source/my_app/my_package_1)
    Checking my_package_2 v0.1.0 (/home/myself/source/my_app/my_package_2)

Here are examples of lints configured in Cargo.toml
https://rust-lang.github.io/rfcs/3389-manifest-lint.html#configurable-lints, but I also haven't found any examples in real projects.

@zoechi Two things:

• allowed-duplicate-crates is a lint configuration option, so you'll want to put allowed-duplicate-crates = [...] in clippy.toml
  • This specific part of the RFC (ability to configure lints using the [lints] table) is under "Future possibilities", so that's not possible yet (at least, to my knowledge)
• allowed-duplicate-crates was very recently added (merged yesterday) and it's not on nightly clippy yet (I believe the next sync is today or tomorrow, so you need to wait a bit, unless you're building clippy from source and you already have the very latest changes)

@y21 very helpful info !
