Struct Underscore 

pub struct Underscore {
    pub spans: [Span; 1],
}

_

Usage: wildcard patterns, inferred types, unnamed items in constants, extern crates, use declarations, and destructuring assignment.

Don’t try to remember the name of this type — use the Token! macro instead.

Fields

spans: [Span; 1]
