Struct per_thread_object::ThreadLocal

pub struct ThreadLocal<T: Send + 'static> { /* fields omitted */ }

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 DEFAULT_PAGE_CAP 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.
