Struct Block

#[non_exhaustive]
pub struct Block<'a, T: Grammar> {
    pub statements: Vec<SpannedStatement<'a, T>>,
    pub return_value: Option<Box<SpannedExpr<'a, T>>>,
}

Expand description

Block of statements.

A block may end with a return expression, e.g., { x = 1; x }.

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.

§statements: Vec<SpannedStatement<'a, T>>

Statements in the block.

§return_value: Option<Box<SpannedExpr<'a, T>>>

The last statement in the block which is returned from the block.
