Struct rustc_hir::AnonConst

pub struct AnonConst {
    pub hir_id: HirId,
    pub def_id: LocalDefId,
    pub body: BodyId,
}

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.

You can check if this anon const is a default in a const param const N: usize = { ... } with tcx.hir().opt_const_param_default_param_def_id(..)

Fields

hir_id: HirId

def_id: LocalDefId

body: BodyId

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<__E: Encoder> Encodable<__E> for AnonConst

fn encode(&self, __encoder: &mut __E)

impl<'hir> From<AnonConst> for Term<'hir>

fn from(c: AnonConst) -> Self

Converts to this type from the input type.

impl<__CTX> HashStable<__CTX> for AnonConstwhere
    __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq<AnonConst> for AnonConst

fn eq(&self, other: &AnonConst) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
