Struct Arm

pub struct Arm {
    pub attrs: Vec<Attribute>,
    pub pat: Pat,
    pub guard: Option<(If, Box<Expr>)>,
    pub fat_arrow_token: FatArrow,

    pub comma: Option<Comma>,
}

One arm of a match expression: 0..=10 => { return true; }.

match n {
    0..=10 => {
        return true;
    }
    // ...
}

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
