pub enum ReallocPlacement {
    MayMove,
    InPlace,
}
🔬 This is a nightly-only experimental API. (allocator_api #32838)

A placement constraint when growing or shrinking an existing allocation.

Variants

MayMove
🔬 This is a nightly-only experimental API. (allocator_api #32838)

The allocator is allowed to move the allocation to a different memory address.

If the allocation does move, it's the responsibility of the allocator to also move the data from the previous location to the new location.

InPlace
🔬 This is a nightly-only experimental API. (allocator_api #32838)

The address of the new memory must not change.

If the allocation would have to be moved to a new location to fit, the reallocation request will fail.
