pub unsafe trait PackedFieldIndexable: PackedField {
// Required methods
fn unpack_scalars(packed: &[Self]) -> &[Self::Scalar];
fn unpack_scalars_mut(packed: &mut [Self]) -> &mut [Self::Scalar];
}Expand description
A PackedField that can be safely cast to indexable slices of scalars.
Not all packed fields can index individual scalar elements. Notably, packed fields of $\mathbb{F}_2$ elements can pack multiple scalars into a single byte.
§Safety
In order for the above relation to be guaranteed, the memory representation of a slice of
PackedExtensionIndexable elements must be the same as a slice of the underlying scalar
elements, differing only in the slice lengths.
Required Methods§
fn unpack_scalars(packed: &[Self]) -> &[Self::Scalar]
fn unpack_scalars_mut(packed: &mut [Self]) -> &mut [Self::Scalar]
Object Safety§
This trait is not object safe.
