🔬This is a nightly-only experimental API. (core_intrinsics)
Expand description

Shuffles two vectors by const indices.

T must be a vector.

U must be a const vector of u32s. This means it must either refer to a named const or be given as an inline const expression (const { ... }).

V must be a vector with the same element type as T and the same length as U.

Returns a new vector such that element i is selected from xy[idx[i]], where xy is the concatenation of x and y. It is a compile-time error if idx[i] is out-of-bounds of xy.
