Struct MatchExpr 

#[non_exhaustive]
pub struct MatchExpr<'arena, 'src> {
    pub subject: &'arena Expr<'arena, 'src>,
    pub arms: ArenaVec<'arena, MatchArm<'arena, 'src>>,
    /* 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: &'arena Expr<'arena, 'src>

Expression being matched.

arms: ArenaVec<'arena, MatchArm<'arena, 'src>>

Match arms in order.

Implementations

impl<'arena, 'src> MatchExpr<'arena, 'src>

pub fn new( subject: &'arena Expr<'arena, 'src>, arms: ArenaVec<'arena, MatchArm<'arena, 'src>>, brace_span: Span, ) -> Self

Builds a MatchExpr from its identifying fields with every other field empty. Set the rest by assignment, as with Param::new.
