Struct ThreadLocal

Source
pub struct ThreadLocal<T: Send + 'static> { /* private fields */ }
Expand description

Per-object thread-local storage

§Capacity

per-thread-object has no max capacity limit, each ThreadLocal instance will create its own memory space instead of using global space.

this crate supports any number of threads, but only the specified number of threads are lock-free.

§Panic when dropping

ThreadLocal will release object at the end of thread. If panic occurs during this process, it may cause a memory leak.
