//! Pluggable implementations for different architectures.

//! The naming of the `u32` and `u64` modules is somewhat unfortunate,
//! since these are also the names of primitive types.  Since types have
//! a different namespace than modules, this isn't a problem to the
//! compiler, but it could cause confusion.
//!
//! However, it's unlikely that the names of those modules would be
//! brought into scope directly, instead of used as
//! `backend::u32::field` or similar.  Unfortunately we can't use
//! `32bit` since identifiers can't start with letters, and the backends
//! do use `u32`/`u64`, so this seems like a least-bad option.
