# Enum std::sync::TryLockError 1.0.0 [−] [src]

    pub enum TryLockError<T> {
        Poisoned(PoisonError<T>),
        WouldBlock,
    }

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

## Variants

`Poisoned(PoisonError<T>)`

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

`WouldBlock`

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
