1//! Implementation of an atomic `u64` cell. On 64 bit platforms, this is a
2//! re-export of `AtomicU64`. On 32 bit platforms, this is implemented using a
3//! `Mutex`.
4
5// `AtomicU64` can only be used on targets with `target_has_atomic` is 64 or greater.
6// Once `cfg_target_has_atomic` feature is stable, we can replace it with
7// `#[cfg(target_has_atomic = "64")]`.
