Struct rustc_ast::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>

impl From<AnonConst> for Term

fn from(v: AnonConst) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
