Struct wayland_client::StateProxy

pub struct StateProxy<'store> { /* fields omitted */ }

A Proxy representing a Store with ongoing borrows

This struct represents a handle to a store from which some values are already mutably borrowed, and as such cannot be touched.

See Store::with_value for detailed explanation of its use.

Methods

impl<'store> StoreProxy<'store>

fn insert<V>(&mut self, value: V) -> Token<V> where
    V: 'static + Any, 

Insert a new value in the proxified store

Returns a clonable token that you can later use to access this value.

fn get<V>(&self, token: &Token<V>) -> &V where
    V: 'static + Any, 

Access value previously inserted in the proxified store

Panics if the provided token corresponds to a value that was removed, or if this value is already borrowed.

fn get_mut<V>(&mut self, token: &Token<V>) -> &mut V where
    V: 'static + Any, 

Mutably access value previously inserted in the proxified store

Panics if the provided token corresponds to a value that was removed, or if this value is already borrowed.

fn remove<V>(&mut self, token: Token<V>) -> V where
    V: 'static + Any, 

Remove a value previously inserted in the proxified store

Panics if the provided token corresponds to a value that was already removed, or if this value is already borrowed.

fn with_value<V, T, F>(&mut self, token: &Token<V>, f: F) -> T where
    F: FnOnce(&mut StoreProxy, &mut V) -> T,
    V: 'static + Any, 

Create a sub-scope with access to a value

Panics if the provided token corresponds to a value that was removed, or if this value is already borrowed.
