Trait swim_mem::resident::ResidentStow

pub trait ResidentStow<'b, L1: Lease, L2: Lease>: Resident {
    fn new_resident_layout(lease: &L1) -> Layout;
    unsafe fn resident_stow(
        src: &mut L1, 
        dst: &mut L2, 
        hold: &dyn Hold<'b>
    ) -> Result<(), HoldError>;
    unsafe fn resident_unstow(src: &mut L1, dst: &mut L2);
}

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.
