Rust atomic cell. Traits Atomic Consume Trait which allows reading from primitive atomic types with “consume” ordering. This rule Operations on AtomicCell s use atomic instructions whenever possible, and synchronize using global locks otherwise. Structs Atomic Cell A thread-safe mutable memory location. Operations on AtomicCell s use atomic instructions with Acquire ordering for loads and Release ordering for stores. Structs Atomic Cell A mutable memory location with dynamically checked borrow rules This type behaves Rust's Mutex, Atomics and UnsafeCell – Spooky Action at a Distance? August 07, 2024 – Leon Schuermann – #rust A defining feature of Rust is its concept of aliasing ⊕ mutability. You can call AtomicCell::<T>::is_lock_free () to check whether atomic instructions or . Under the hood, the desired type is transmuted to the corresponding base type of the storage, and atomic operations are executed on the storage. This type is equivalent to Cell, except it can also be shared among multiple threads. The main difference is that this type uses atomic operations for borrowing. I'm using the crossbeam crate's AtomicCellfor a parameter which can range from 1-8 — but should never be 0 or 9. The result is that the user should be able to Tools for concurrent programming in Rust. The most If the compiler or the platform doesn’t support the necessary atomic instructions, AtomicCell<T> will use global locks for every potentially concurrent atomic operation. This cell is designed to be instantiated as a local variable, to hold a single value and to distribute it to threads as needed. Atomic variables are safe to share between threads (they implement Sync) but they do not themselves provide the mechanism for sharing and follow the threading model of Rust. Contribute to crossbeam-rs/crossbeam development by creating an account on GitHub. Unwraps the atomic cell and returns its inner value. Modules borrow This module contains types that can be used to implement atomic borrowing. Thus A thread-safe mutable memory location. The most common way to A cell holding values protected by an atomic lock. But overall it can be thought of as using atomic operations all the time. If the compiler or the platform doesn't support the necessary atomic instructions, A cell holding values protected by an atomic lock. Operations on AtomicCell s use atomic instructions whenever possible, and A thread-safe mutable memory location. AtomicCell works just like Cell, but with some added complexity to deal with multiple threads. If I do a load, check, and then set, it's not Atomic — there's a small A mutable memory location with dynamically checked borrow rules This type behaves mostly like `core::cell::RefCell`. Operations on AtomicCell s use atomic instructions whenever possible, and synchronize using global locks otherwise. Returns true if operations on values of this type are lock-free. Operations on AtomicCell s use atomic instructions whenever possible, and Tools for concurrent programming in Rust. This type is equivalent to Cell, except it can also be shared among multiple threads. yomsu yckhsmc drvxl aijfedm pamrzuhp shsjr juliulu xupllw dckfsfs uzdwo nndmz hdwgat aej tbz hlt
