An arm of a 'match'.

E.g., 0..=10 => { println!("match!") } as in

match 123 {
    0..=10 => { println!("match!") },
    _ => { println!("no match!") },


attrs: Vec<Attribute>pat: P<Pat>

Match arm pattern, e.g. 10 in match foo { 10 => {}, _ => {} }

guard: Option<P<Expr>>

Match arm guard, e.g. n > 10 in match foo { n if n > 10 => {}, _ => {} }

body: P<Expr>

Match arm body.
