TryLockError in std::sync - Rust
Description: An enumeration of possible errors associated with a `TryLockResult` which can occur while trying to acquire a lock, from the `try_lock` method on a `Mutex` or the `try_read` and `try_write` methods on an `RwLock`.

Expand description

An enumeration of possible errors associated with a `TryLockResult` which can occur while trying to acquire a lock, from the `try_lock` method on a `Mutex` or the `try_read` and `try_write` methods on an `RwLock`.

## Variants§

§1.0.0

### Poisoned(PoisonError<T>)

The lock could not be acquired because another thread failed while holding the lock.

§1.0.0

### WouldBlock

The lock could not be acquired at this time because the operation would otherwise block.
