Crate thin_slice

An owned slice that tries to use only one word of storage.

ThinBoxedSlice<T> can be used in place of Box<[T]> on the x86_64 architecture to hold ownership of a slice when it’s important to reduce memory usage of the box itself. When the slice length is less than 0xffff, a single word is used to encode the slice pointer and length. When it is greater than 0xffff, a heap allocation is used to store the fat pointer representing the slice.

A ThinBoxedSlice<T> is always created by converting from a Box<[T]>.

On any architecture other than x86_64, a ThinBoxedSlice<T> will simply use a Box<[T]> internally.

Examples

Creating a ThinBoxedSlice:

let fat_pointer = vec![10, 20, 30].into_boxed_slice();
let thin_pointer: ThinBoxedSlice<_> = fat_pointer.into();
