Enum Statement

Source

#[non_exhaustive]
pub enum Statement<'a, T: Grammar> {
    Expr(SpannedExpr<'a, T>),
    Assignment {
        lhs: SpannedLvalue<'a, T::Type<'a>>,
        rhs: Box<SpannedExpr<'a, T>>,
    },
}

Expand description

Statement: an expression or a variable assignment.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

§

Expr(SpannedExpr<'a, T>)

Expression, e.g., x + (1, 2).

§

Assignment

Assigment, e.g., (x, y) = (5, 8).

Fields

§lhs: SpannedLvalue<'a, T::Type<'a>>

LHS of the assignment.

§rhs: Box<SpannedExpr<'a, T>>

RHS of the assignment.
