Struct StreamBuilder 

pub struct StreamBuilder;

Builds from a stream of values — the reference’s StreamBuilder, over BuildContext::use_stream: the work is given a StreamSink and adds its values to it.

Implementations

impl StreamBuilder

pub fn new<K, T, F>( key: K, make: impl Fn(&K, StreamSink<T>) -> F + 'static, build: impl Fn(&BuildContext<'_>, AsyncSnapshot<T>) -> Box<dyn Widget> + 'static, ) -> Component

where K: Clone + PartialEq + 'static, T: Clone + MaybeSend + 'static, F: Future<Output = ()> + MaybeSend + 'static,

A component that runs make(&key, sink) once per key, and builds from the latest value it gave.
