Struct ConstAlloc 

pub struct ConstAlloc<'tcx> {
    pub alloc_id: AllocId,
    pub ty: Ty<'tcx>,
}

Evaluated Constants Represents the result of const evaluation via the eval_to_allocation query. Not to be confused with ConstAllocation, which directly refers to the underlying data! Here we indirect via an AllocId.

Fields

alloc_id: AllocId

The value lives here, at offset 0, and that allocation definitely is an AllocKind::Memory (so you can use AllocMap::unwrap_memory).

ty: Ty<'tcx>

Trait Implementations

impl<'tcx> Clone for ConstAlloc<'tcx>

fn clone(&self) -> ConstAlloc<'tcx>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ConstAlloc<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<'tcx>> Decodable<__D> for ConstAlloc<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<'tcx>> Encodable<__E> for ConstAlloc<'tcx>

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

impl<'tcx> EraseType for ConstAlloc<'tcx>

type Result = [u8; 16]

impl<'tcx> Hash for ConstAlloc<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for ConstAlloc<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl<'tcx> PartialEq for ConstAlloc<'tcx>

fn eq(&self, other: &ConstAlloc<'tcx>) -> 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.

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.
