Pavel Aslanov 6c6d948385 adds Mutex extentsion method .with ... Summary: I find that it is common pattern ``` // create unnecessary to reduce scope of lock guard let output = { let mut value = mutex_value.lock().expect("lock poisoned"); ... // do some stuff here }; ``` This extension simplifies this pattern to ``` let output = mutex_value.with(|value| /* do some stuff here */); ``` Reviewed By: Imxset21, farnz Differential Revision: D15577135 fbshipit-source-id: 6b22b20dda79e532ff5ec8ce75cda8b1c1404368		2019-05-31 09:28:54 -07:00
