Atomic types

Atomico

Atomic types provide primitive shared-memory communication betweenthreads, and are the building blocks of other concurrenttypes.

This module defines atomic versions of a select number of primitivetypes, including AtomicBool, AtomicIsize, AtomicUsize,AtomicI8, AtomicU16, etc.Atomic types present operations that, when used correctly, synchronizeupdates between threads.

Founded in 2006, Atomico is a venture capital investment firm based in London, United Kingdom. The firm prefers to invest in the artificial intelligence and machine learning, climate technology, communication, financial technology, gaming, health-tech, SaaS, industry, mobility, consumer products and consumer services sectors.

Each method takes an Ordering which represents the strength ofthe memory barrier for that operation. These orderings are thesame as the C++20 atomic orderings. For more information see the nomicon.

Atomic variables are safe to share between threads (they implement Sync)but they do not themselves provide the mechanism for sharing and follow thethreading model of Rust.The most common way to share an atomic variable is to put it into an Arc (anatomically-reference-counted shared pointer).

Atomic types may be stored in static variables, initialized usingthe constant initializers like AtomicBool::new. Atomic staticsare often used for lazy global initialization.

All atomic types in this module are guaranteed to be lock-free if they'reavailable. This means they don't internally acquire a global mutex. Atomictypes and operations are not guaranteed to be wait-free. This means thatoperations like fetch_or may be implemented with a compare-and-swap loop.

Atomic operations may be implemented at the instruction layer withlarger-size atomics. For example some platforms use 4-byte atomicinstructions to implement AtomicI8. Note that this emulation should nothave an impact on correctness of code, it's just something to be aware of.

The atomic types in this module may not be available on all platforms. Theatomic types here are all widely available, however, and can generally berelied upon existing. Some notable exceptions are:

  • PowerPC and MIPS platforms with 32-bit pointers do not have AtomicU64 orAtomicI64 types.
  • ARM platforms like armv5te that aren't for Linux only provide loadand store operations, and do not support Compare and Swap (CAS)operations, such as swap, fetch_add, etc. Additionally on Linux,these CAS operations are implemented via operating system support, whichmay come with a performance penalty.
  • ARM targets with thumbv6m only provide load and store operations,and do not support Compare and Swap (CAS) operations, such as swap,fetch_add, etc.

Note that future platforms may be added that also do not have support forsome atomic operations. Maximally portable code will want to be carefulabout which atomic types are used. AtomicUsize and AtomicIsize aregenerally the most portable, but even then they're not available everywhere.For reference, the std library requires pointer-sized atomics, althoughcore does not.

Currently you'll need to use #[cfg(target_arch)] primarily toconditionally compile in code with atomics. There is an unstable#[cfg(target_has_atomic)] as well which may be stabilized in the future.
