pub enum ReallocPlacement {
    MayMove,
    InPlace,
}

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

A placement constraint when growing or shrinking an existing allocation.

Variants

MayMove

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

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)

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.
