Module std::thread_localStable [-] [+] [src]

Thread local storage

This module provides an implementation of thread local storage for Rust programs. Thread local storage is a method of storing data into a global variable which each thread in the program will have its own copy of. Threads do not share this data, so accesses do not need to be synchronized.

At a high level, this module provides two variants of storage:

Both forms of thread local storage provide an accessor function, with, which will yield a shared reference to the value to the specified closure. Thread local keys only allow shared access to values as there is no way to guarantee uniqueness if a mutable borrow was allowed. Most values will want to make use of some form of interior mutability through the Cell or RefCell types.
