A relocatable Resident of a raw memory Lease.

Required methods

fn new_resident_layout(lease: &L1) -> Layout[+]

Returns the preferred memory layout of a move destination for the resident of the lease.

unsafe fn resident_stow(
    src: &mut L1,
    dst: &mut L2,
    hold: &dyn Hold<'b>
) -> Result<(), HoldError>[+]

Relocates the resident from the src lease to the dst lease. Leaves the src lase in its original state on failure.

unsafe fn resident_unstow(src: &mut L1, dst: &mut L2)[+]

Reverts the most recent resident_stow operation by relocating the resident of the dst lease back to the src lease.
