Declare a new thread local storage key of type std::thread::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 std::cell::RefCell;
thread_local! {
pub static FOO: RefCell<u32> = RefCell::new(1);
#[allow(unused)]
static BAR: RefCell<f32> = RefCell::new(1.0);
}
