Struct NoCowGuard 

Source 
pub struct NoCowGuard<'lock, ITEM: Send + Debug> { /* private fields */ }
Expand description

Guards the exclusive lock. During this lock, any CoW operations are blocked.

  • The current thread must not borrow the locking instance.

  • No other thread (except calling) should already hold exclusive lock.

  • Must not be poisoned.
