This crate contains common utilities for crates within the awint system.
Some of these are highly unsafe macros that were only placed here because
#[macro_export] unconditionally causes macros to be publicly accessible.
To prevent them from being accessible from intended user-facing crates, this
_internals crate was made. The safety requirements of these macros may
change over time, so this crate should never be used outside of this system.
