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>

Trait Implementations

impl Clone for AnonConst

fn clone(&self) -> AnonConst

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnonConst

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for AnonConst

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

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.
