Struct UpdaterEffect 

pub struct UpdaterEffect<T, I, C, U> { /* private fields */ }

Internal updater effect handle. Prefer the associated constructors over the free functions.

Implementations

impl UpdaterEffect<(), (), (), ()>

Create an effect updater that runs on_change when any signals that subscribe during the run of compute are updated. compute is immediately run only once, and its value is returned from UpdaterEffect::new.

pub fn new<R>( compute: impl Fn() -> R + 'static, on_change: impl Fn(R) + 'static, ) -> R

where R: 'static,

Create an effect updater that runs on_change when any signals that subscribe during the run of compute are updated. compute is immediately run only once, and its value is returned from UpdaterEffect::new.

pub fn new_stateful<T, R>( compute: impl Fn(Option<T>) -> (R, T) + 'static, on_change: impl Fn(R, T) -> T + 'static, ) -> R

where T: Any + 'static, R: 'static,

Create an effect updater that runs on_change when any signals within compute subscribe to changes. compute is immediately run and its return value is returned.
