Struct TryLockError

pub struct TryLockError(/* private fields */);

Available on crate feature sync only.

Error returned from the Mutex::try_lock, RwLock::try_read and RwLock::try_write functions.

Mutex::try_lock operation will only fail if the mutex is already locked.

RwLock::try_read operation will only fail if the lock is currently held by an exclusive writer.

RwLock::try_write operation will only fail if the lock is currently held by any reader or by an exclusive writer.
