std::sync::PoisonError
Struct std::sync::PoisonError
pub struct PoisonError<T> { /* fields omitted */ }
A type of error which can be returned whenever a lock is acquired.
Both Mutexes and RwLocks are poisoned whenever a thread fails while the lock is held. The precise semantics for when a lock is poisoned is documented on each lock, but once a lock is poisoned then all future acquisitions will return this error.
Methods
impl<T> PoisonError<T>
[src]
fn new(guard: T) -> PoisonError<T>1.2.0
Creates a PoisonError.
This is generally created by methods like Mutex::lock or RwLock::read.
fn into_inner(self) -> T1.2.0
Consumes this error indicating that a lock is poisoned, returning the underlying guard to allow access regardless.
fn get_ref(&self) -> &T1.2.0
Reaches into this error indicating that a lock is poisoned, returning a reference to the underlying guard to allow access regardless.
fn get_mut(&mut self) -> &mut T1.2.0
Reaches into this error indicating that a lock is poisoned, returning a mutable reference to the underlying guard to allow access regardless.
