Struct ThreadLocalMut

Source 
pub struct ThreadLocalMut<T: Send>(/* private fields */);
Expand description

Creates a “scratch space” within each thread with mutable access.

This is mainly meant to be used as an optimization to avoid unnecessary allocs/frees within rayon code. You only pay for allocation of this scratch space once per thread.

Since the space is local to each thread you also don’t have to worry about atomicity.
