Struct TyConst

pub struct TyConst {
    pub(crate) kind: TyConstKind,
    pub id: TyConstId,
}

Represents a constant in the type system

Fields

kind: TyConstKind

id: TyConstId

Implementations

impl TyConst

pub fn new(kind: TyConstKind, id: TyConstId) -> TyConst

pub fn kind(&self) -> &TyConstKind

Retrieve the constant kind.

pub fn try_from_target_usize(val: u64) -> Result<Self, Error>

Creates an interned usize constant.

pub fn eval_target_usize(&self) -> Result<u64, Error>

Try to evaluate to a target usize.

Trait Implementations

impl Clone for TyConst

fn clone(&self) -> TyConst

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TyConst

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

Formats the value using the given formatter.

impl PartialEq for TyConst

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl RustcInternal for TyConst

type T<'tcx> = Const<'tcx>

fn internal<'tcx>( &self, tables: &mut Tables<'_>, tcx: TyCtxt<'tcx>, ) -> Self::T<'tcx>

impl Serialize for TyConst

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Visitable for TyConst

fn visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

fn super_visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

impl Eq for TyConst

impl StructuralPartialEq for TyConst

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.
