[−][src]Crate ticketed_lock
Ticketed lock.
Ticketed lock is similar to RwLock, except that the acquisition of the lock is split:
- obtaining a ticket, which has to be done on the same thread as the locked storage
- waiting on a ticket, which puts the current thread to sleep until the ticket is due. That moment comes when all the previous tickets are processed.
- working with the data behind a read/lock guard
- when the guard is freed, it allows the following tickets to become active
A ticket can be moved between threads or even just lost.
Consecutive read-only tickets do not guarantee a particular lock order.
All the ticket counting is done based on Arc
primitives, and the only unsafe code that this library has is for accessing the actual data behind a guard.
