Implementations

impl<M> Sub<M>

pub fn none() -> Self

pub fn tick(id: u64, every: Duration, produce: fn() -> M) -> Self

pub fn stream( id: u64, name: &'static str, every: Duration, produce: fn() -> M, ) -> Self

pub fn websocket( id: u64, url: &'static str, every: Duration, produce: fn() -> M, ) -> Self

pub fn map_msg(inner: Sub<()>, map: fn(()) -> M) -> Self

Wrap a Sub<()> and map each firing into M (Elm Sub.map).

pub fn map<N>(self, _f: fn(M) -> N) -> Sub<N>

Map batched subscription outputs. For leaf ticks/streams, use explicit produce fns or Self::map_msg at the target action type.

pub fn batch(subs: impl IntoIterator<Item = Sub<M>>) -> Self

pub fn id(&self) -> Option<u64>

Trait Implementations

impl<M: Clone> Clone for Sub<M>

fn clone(&self) -> Sub<M>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M: Debug> Debug for Sub<M>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<M: Eq> Eq for Sub<M>

impl<M: PartialEq> PartialEq for Sub<M>

fn eq(&self, other: &Sub<M>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
