Expand description
Macro equivalent of <[&[T]]>::concat
, which takes a constant as an argument.
This acts like a compile-time-evaluated version of this function:
pub const fn slice_concat<T>(slices: &'static [&'static [T]]) -> [T; LEN]
where
T: Copy
Where LEN
is the summed length of all inner slices.
ยงExample
use konst::slice::slice_concat;
const S: &[&[u8]] = &[&[3, 5], &[8, 13, 21, 34]];
assert_eq!(slice_concat!(u8, S), [3, 5, 8, 13, 21, 34]);
assert_eq!(slice_concat!(u8, &[]), []);
assert_eq!(slice_concat!(u8, &[&[], &[1, 2, 3], &[4, 5]]), [1, 2, 3, 4, 5]);
