Struct per_thread_object::ThreadLocal

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

Per-object thread-local storage

Cloneable

ThreadLocal uses built-in reference counting, so it is usually not necessary to use Arc.

Capacity

per-thread-object has no 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 N threads are lock-free.

Panic when dropping

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

Implementations
