Struct Subscribing 

pub struct Subscribing { /* private fields */ }

The pollable state of a Consumer::subscribe; awaited via the kio::Pending wrapper, whose DerefMut exposes Self::update.

Implementations

impl Subscribing

pub fn poll_ok(&self, waiter: &Waiter) -> Poll<Result<Subscriber>>

Poll until the peer confirms the subscription, yielding the Subscriber. Errors if the track is aborted or not found.

pub fn update(&mut self, subscription: Subscription) -> Result<()>

Change the subscription preferences before (or after) it resolves.

Returns Error::Closed if the track already ended; the update is meaningless at that point and can usually be ignored.

Trait Implementations

impl Pollable for Subscribing

type Output = Result<Subscriber, Error>

The value the computation resolves to.

fn poll(&self, waiter: &Waiter) -> Poll<Self::Output>

Poll for the output, registering waiter with the relevant channels if not yet ready.
