Struct rustc_middle::mir::interpret::ConstAllocation

pub struct ConstAllocation<'tcx, Prov = AllocId, Extra = ()>(pub Interned<'tcx, Allocation<Prov, Extra>>);

Interned types generally have an Outer type and an Inner type, where Outer is a newtype around Interned<Inner>, and all the operations are done on Outer, because all occurrences are interned. E.g. Ty is an outer type and TyS is its inner type.

Here things are different because only const allocations are interned. This means that both the inner type (Allocation) and the outer type (ConstAllocation) are used quite a bit.

impl<'tcx, Prov: Ord, Extra: Ord> Ord for ConstAllocation<'tcx, Prov, Extra>

fn cmp(&self, other: &ConstAllocation<'tcx, Prov, Extra>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere

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.
