[−][src]Struct epoxy_streams::ReadonlyReactiveValue
Holds the latest value emitted by a stream.
ReactiveValues automatically unsubscribe from the stream when they are destroyed, preventing the kinds of memory leaks common in reactive programming.
Examples
use epoxy_streams::ReactiveValue; let stream_host: epoxy_streams::Sink<i32> = epoxy_streams::Sink::new(); let stream = stream_host.get_stream(); let reactive_value = stream.map(|val| val * 100).to_reactive_value(); assert_eq!(*reactive_value.get(), 0); stream_host.emit(1); assert_eq!(*reactive_value.get(), 100); stream_host.emit(3); assert_eq!(*reactive_value.get(), 300);
use epoxy_streams::ReactiveValue; let stream_host: epoxy_streams::Sink<i32> = epoxy_streams::Sink::new(); let stream = stream_host.get_stream(); let reactive_value = stream.map(|val| val * 100).to_reactive_value_with_default(1000); assert_eq!(*reactive_value.get(), 1000); stream_host.emit(100); assert_eq!(*reactive_value.get(), 10000);
