[−][src]Struct option_lock::OptionGuard

pub struct OptionGuard<'a, T> { /* fields omitted */ }

A write guard for the value of an OptionLock

Implementations

impl<T, '_> OptionGuard<'_, T>[src]

pub fn as_ref(&self) -> Option<&T>[src]

Obtain a shared reference to the contained value, if any.

pub fn as_mut_ref(&mut self) -> Option<&mut T>[src]

Obtain an exclusive reference to the contained value, if any.

pub fn is_none(&self) -> bool[src]

Check if the lock contains None.

pub fn is_some(&self) -> bool[src]

Check if the lock contains Some(T).

pub fn replace(&mut self, value: T) -> Option<T>[src]

Replace the value in the lock, returning the previous value, if any.

pub fn take(&mut self) -> Option<T>[src]

Take the current value from the lock, if any.
