Declare a new thread local storage key of type LocalKey.

Syntax

The macro wraps any number of static declarations and makes them thread local. Publicity and attributes for each static are allowed. Example:

use core::cell::RefCell;
thread_local! {
    pub static FOO: RefCell<u32> = RefCell::new(1);

    #[allow(unused)]
    static BAR: RefCell<f32> = RefCell::new(1.0);
}
