[−][src]Struct per_thread_object::ThreadLocal
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 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.
