VecLayout

Struct VecLayout 

Source
pub struct VecLayout;
Expand description

Enables storing a vector into an ArcSlice without requiring the allocation of an inner Arc, as long as there is a single instance.

As soon as the ArcSlice is cloned (or subsliced), then an inner Arc is allocated. As a consequence, when oom-handling feature is not enabled, ArcSlice<S, VecLayout> doesn’t implement Clone.

assert_eq!(size_of::<ArcBytes<VecLayout>>(), 4 * size_of::<usize>());
assert_eq!(size_of::<ArcBytesMut<VecLayout>>(), 4 * size_of::<usize>());
