Struct option_lock::OptionRead

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

A read guard for the value of a populated OptionLock

Implementations

impl<'a, T: 'a> OptionRead<'a, T>

pub fn try_lock(
    read: OptionRead<'a, T>
) -> Result<OptionGuard<'a, T>, OptionRead<'a, T>>

Try to upgrade a read guard to a write guard.

This requires that there are no other active readers.

pub fn try_take(read: OptionRead<'a, T>) -> Result<T, OptionRead<'a, T>>

Try to take the contained value from an acquired read guard.

This requires that there are no other active readers.
