atomic_refcell

A thread-safe analogue of RefCell for Rust.

Overview

AtomicRefCell provides RefCell-like borrow semantics (checked at runtime, with immutable and mutable borrows) for values shared across threads. It is designed for use cases where the caller can guarantee that mutable and immutable borrows never overlap concurrently, but still requires a Sync type.

The crate is no_std compatible.

Features

Feature	Description
portable-atomic	Use portable-atomic instead of core::sync::atomic. Enables support for targets without native atomic compare-and-swap instructions (e.g. thumbv6m-none-eabi).
serde	Implement Serialize and Deserialize for AtomicRefCell<T>.

Minimum Supported Rust Version (MSRV)

Rust 1.60 or later is required.
