Struct SharedReducer 

pub struct SharedReducer<'a, G, L = G, F: Fn(&mut G, &L) = fn(&mut G, &L)> { /* private fields */ }

A shareable copy of a Reducer containing a local value and implementing Clone.

The local value can be accessed with AsRef and AsMut implementations.

When a SharedReducer is dropped, the local value will be reduced into the global value. If the mutex is poisoned (e.g., due to a panic in another thread), the reduction will still be performed on the recovered value.

Implementations

impl<G: Clone, L, F: Fn(&mut G, &L)> SharedReducer<'_, G, L, F>

pub fn peek(&self) -> G

Returns the current global value.

This method delegates to Reducer::peek.

Trait Implementations

impl<G, L, F: Fn(&mut G, &L)> AsMut<L> for SharedReducer<'_, G, L, F>

fn as_mut(&mut self) -> &mut L

Returns a mutable reference to the local value.

impl<G, L, F: Fn(&mut G, &L)> AsRef<L> for SharedReducer<'_, G, L, F>

fn as_ref(&self) -> &L

Returns a reference to the local value.

impl<G, L: Default, F: Fn(&mut G, &L)> Clone for SharedReducer<'_, G, L, F>

fn clone(&self) -> Self

Returns a copy sharing the same global value and with local value initialized to the default value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<G: Debug, L: Debug, F: Fn(&mut G, &L)> Debug for SharedReducer<'_, G, L, F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<G, L, F: Fn(&mut G, &L)> Drop for SharedReducer<'_, G, L, F>

fn drop(&mut self)

Reduces the local value into the global value.
