Enum Assignable

pub enum Assignable {
    ElementAccess(ElementAccess),
    Deref {
        star_token: StarToken,
        expr: Box<Expr>,
    },
}

Left-hand side of an assignment.

Variants

ElementAccess(ElementAccess)

A single variable or a path to a part of an aggregate. E.g.:

• my_variable
• array[0].field.x.1

Note that within the path, we cannot have dereferencing (except, of course, in expressions inside of array index operator). This is guaranteed by the grammar. E.g., an expression like this is not allowed by the grammar: my_struct.*expr

Deref

Dereferencing of an arbitrary reference expression. E.g.:

• *my_ref
• **if x > 0 { &mut &mut a } else { &mut &mut b }

Fields

star_token: StarToken

expr: Box<Expr>
