Struct MatchExpr 

#[non_exhaustive]
pub struct MatchExpr {
    pub subject: Box<Expr>,
    pub arms: Box<[MatchArm]>,
    /* private fields */
}

A match expression.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

subject: Box<Expr>

Matched expression.

arms: Box<[MatchArm]>

Match arms.

Implementations

impl MatchExpr

pub fn new(subject: Box<Expr>, arms: Box<[MatchArm]>, brace_span: Span) -> Self
