Function leptos_reactive::create_signal_from_stream

pub fn create_signal_from_stream<T>(
    stream: impl Stream<Item = T> + Unpin + 'static
) -> ReadSignal<Option<T>>

Creates a signal that always contains the most recent value emitted by a Stream. If the stream has not yet emitted a value since the signal was created, the signal’s value will be None.

Note: If used on the server side during server rendering, this will return None immediately and not begin driving the stream.
