Struct ShardState 

pub struct ShardState<T> { /* private fields */ }

Reactive state owned by a route or router controller.

Reads subscribe the current UI phase to changes. Handles remain valid while their owner lives and must be accessed on the owning UI session.

Implementations

impl<T: Send + Sync + 'static> ShardState<T>

pub fn with<R>(&self, f: impl FnOnce(&T) -> R) -> R

Reads the value and subscribes the active UI phase to its changes.

pub fn with_mut<R>(&self, f: impl FnOnce(&mut T) -> R) -> R

Updates the value and invalidates its UI consumers.

pub fn try_with<R>(&self, f: impl FnOnce(&T) -> R) -> Result<R, ShardStateError>

Reads live state, reporting an expired controller or route.

pub fn try_with_mut<R>( &self, f: impl FnOnce(&mut T) -> R, ) -> Result<R, ShardStateError>

Updates live state, reporting an expired controller or route.

pub fn get(&self) -> T

where T: Clone,

Returns a cloned value.

pub fn set(&self, value: T)

Replaces the value and invalidates its UI consumers.
