Macro rustc_lint::passes::expand_lint_pass_methods

macro_rules! expand_lint_pass_methods {
    ($context:ty, [$($(#[$attr:meta])* fn $name:ident($($param:ident: $arg:ty),*);)*]) => { ... };
}

Trait for types providing lint checks.

Each check method checks a single syntax node, and should not invoke methods recursively (unlike Visitor). By default they do nothing.
