Rust atomic enum. e. An attribute to create an atomic wrapper around a C-style enum. Creates an atomic wrapper around a C-style enum. A place for all things related to the Rust programming language—an open-source systems language that emphasizes performance, reliability, and productivity. Apr 8, 2025 · In this episode of Crust of Rust, we go over Rust's atomic types, including the mysterious Ordering enum. Atomically Sized Trait describing types that are atomically sized, i. Atomic Numeric Trait describing structs that implement atomic integer operations. it’s possible to perform atomic . This got me thinking about if there are ways to express these use cases Sep 17, 2020 · Rust doesn't do ducktyping (except sorta kinda in macros like you'd expect). Atomic types present operations that, when used correctly, synchronize updates between threads. This module defines atomic versions of a select number of primitive types, including AtomicBool, AtomicIsize, AtomicUsize, AtomicI8, AtomicU16, etc. Mar 27, 2025 · The documentation for this module describes atomic types as follows: Atomic types in Rust provide primitive shared-memory communication between threads and serve as the foundation for atomic_enum An attribute to create an atomic wrapper around a C-style enum. Atomic memory orderings Memory orderings limit the ways that both the compiler and CPU may reorder instructions around atomic operations. Mar 27, 2025 · Atomic Primitives in Rust In Rust, atomic types are located in the std::sync::atomic module. it’s possible to perform atomic Sep 17, 2020 · Rust doesn't do ducktyping (except sorta kinda in macros like you'd expect). Mar 2, 2026 · Memory orderings specify the way atomic operations synchronize memory. For Feb 21, 2024 · An attribute to create an atomic wrapper around a C-style enum Mar 27, 2025 · An in-depth guide to atomic types, operations, and memory ordering in Rust concurrency. Internally, the generated wrapper uses an AtomicUsize to store the value. There's probably a better solution, so what is it that you're trying to solve with these enums? Enums Ordering Atomic memory orderings Traits Atomic Trait describing an atomic version of an atomically-sized type. The atomic operations have the same semantics as the equivalent operations of AtomicUsize. GitHub Gist: instantly share code, notes, and snippets. At its most restrictive, "sequentially consistent" atomics allow neither reads nor writes to be moved either before or after the atomic operation; on the other end "relaxed" atomics allow all reorderings. Rust's memory orderings are the same as LLVM's. There's probably a better solution, so what is it that you're trying to solve with these enums? Jan 24, 2014 · How do you import and reference enum types from the Rust std lib? I'm trying to use the Ordering enum from the std::sync::atomics module. My attempts so far have all ended in failure: use std::s A place for all things related to the Rust programming language—an open-source systems language that emphasizes performance, reliability, and productivity. The documentation for this module describes atomic types as follows: Atomic types in Rust provide primitive shared-memory communication between threads and serve as the foundation for building other concurrency types. Atomic Bitwise Trait describing structs that implement atomic bitwise operations. In particular, we explore the std::sync::atomic module, and look at how its components can be used to implement concurrency primitives like mutexes. In its weakest Ordering::Relaxed, only the memory directly touched by the operation is synchronized. May 20, 2021 · With atomic::AtomicUsize and other atomics I have seen a lot of cases of packing extra information into the value: using a sentinel value (0, -1, MAX, null) to indicate that a static value is not yet initialized, reserving certain bits as status fields, recreating enums with const UNINIT = 0, READY = 1, WAITING = 2 etc. Mar 2, 2026 · This module defines atomic versions of a select number of primitive types, including AtomicBool, AtomicIsize, AtomicUsize, AtomicI8, AtomicU16, etc. Enums Ordering Atomic memory orderings Traits Atomic Trait describing an atomic version of an atomically-sized type. atomic enum in rust. ucv qqc bdywirb soiy prnnme lvbn omla bqzjlofx becjg tuxc
