-//! Trivial, internal byte transmutation.
-//!
-//! A dependency like bytemuck would give us extra assurance of the safety but overall would not
-//! reduce the amount of total unsafety. We don't use it in the interface where the traits would
-//! really become useful.
-//!
-//! SAFETY: These are benign casts as we apply them to fixed size integer types only. All of them
-//! are naturally aligned, valid for all bit patterns and their alignment is surely at most their
-//! size (we assert the latter fact since it is 'implementation defined' if following the letter of
-//! the unsafe code guidelines).
-//!
-//! TODO: Would like to use std-lib here.
