Struct syntax::ast::AnonConst

pub struct AnonConst {
    pub id: NodeId,
    pub value: P<Expr>,
}

A constant (expression) that's not an item or associated item, but needs its own DefId for type-checking, const-eval, etc. These are usually found nested inside types (e.g. array lengths) or expressions (e.g. repeat counts), and also used to define explicit discriminant values for enum variants.

Fields

id: NodeId

value: P<Expr>
