The tracking issue for this feature is: #44690

Tool lints let you use scoped lints, to allow, warn, deny or forbid lints of certain tools.

Currently clippy is the only available lint tool.

It is recommended for lint tools to implement the scoped lints like this:

  • #[_(TOOL_NAME::lintname)]: for lint names
  • #[_(TOOL_NAME::lintgroup)]: for groups of lints
  • #[_(TOOL_NAME::all)]: for (almost1) all lints

An example



fn main() {
    let v = vec![0; 10];
    let _ = v.into_iter().filter(|&x| x < 1).map(|x| x + 1).collect::<Vec<_>>();
    println!("No filter_map()!");

Some defined lint groups can be excluded here.
