Function map_vec_in_place

source 
pub fn map_vec_in_place<A, B, F>(values: Vec<A>, map: F) -> Vec<B>
where
    A: ArrayCast,
    B: ArrayCast<Array = A::Array>,
    F: FnMut(A) -> B,
Expand description

Map values of color A to values of color B without creating a new Vec.

This uses the guarantees of ArrayCast to reuse the allocation.
