pub fn packed_from_fn_with_offset<P: PackedField>(
offset: usize,
f: impl FnMut(usize) -> P::Scalar,
) -> P
Expand description
Construct a packed field element from a function that returns scalar values by index with the
given offset in packed elements. E.g. if offset
is 2, and WIDTH
is 4, f(9)
will be used
to set the scalar at index 1 in the packed element.
