AnonConst in rustc_ast::ast - Rust (original) (raw)

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

Expand description

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.
