Crate thin_boxed_slice
source ·Expand description
ThinBoxedSlice stores the size of the slice before the content of the slice, so that size_of::<ThinBoxedSlice> is only the size of a pointer:
use core::mem::size_of;
use thin_boxed_slice::ThinBoxedSlice;
assert_eq!(size_of::<ThinBoxedSlice<u8>>(), size_of::<*mut u8>());§Examples
use thin_boxed_slice::ThinBoxedSlice;
use core::ops::Deref;
let data = &[1, 2, 3];
let result = ThinBoxedSlice::<i32>::from(data);
assert_eq!(result.len(), 3);
assert_eq!(result.deref(), data);
