Struct LockedValueRef 

pub struct LockedValueRef<'a, T, L>
where
    L: LockValue<T>,
{ /* private fields */ }

A reference to a value behind a lock.

This struct allows querying locked data without copying. The lock is acquired when needed and released when dropped.

Implementations

impl<'a, T, L> LockedValueRef<'a, T, L>

where L: LockValue<T>,

pub fn new(lock: &'a L) -> LockedValueRef<'a, T, L>

pub fn with_value<F, R>(&self, f: F) -> Option<R>

where F: FnOnce(&T) -> R,

Execute a function with access to the locked value.

pub fn map<F, R>(&self, f: F) -> Option<R>

where F: FnOnce(&T) -> R,

Try to get a value from the lock by applying a function.

pub fn matches<F>(&self, predicate: F) -> bool

where F: FnOnce(&T) -> bool,

Check if the locked value matches a predicate.
