Struct ExprMatchBranch

Source
#[non_exhaustive]
pub struct ExprMatchBranch { pub pat: Pat, pub condition: Option<(If, Expr)>, pub rocket: Rocket, pub body: Expr, }
Expand description

A match branch.

Fields (Non-exhaustive)§

This struct is marked as 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.
§pat: Pat

The pattern to match.

§condition: Option<(If, Expr)>

The branch condition.

§rocket: Rocket

The rocket token.

§body: Expr

The body of the match.
