# `tool_lints`

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

    #![feature(tool_lints)]

    #![warn(clippy::pedantic)]

    #[allow(clippy::filter_map)]
    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.
