Function create_read_slice

pub fn create_read_slice<T, O>(
    signal: RwSignal<T>,
    getter: impl Fn(&T) -> O + Copy + Send + Sync + 'static,
) -> Signal<O>
where
    T: Send + Sync + 'static,
    O: PartialEq + Send + Sync + 'static,

Takes a memoized, read-only slice of a signal. This is equivalent to the read-only half of create_slice.
