Overview

ticketed_lock is a Ticketed lock system - allows one to separate lock request from the actual waiting.

Affected versions of this package are vulnerable to Memory Corruption. This crate unconditionally implemented Send for ReadTicket<T> & WriteTicket<T>. This allows to send non-Send T to other threads. This can create data races by cloning types with internal mutability and sending them to other threads (as T of ReadTicket<T>/WriteTicket<T>).
