Implementations

source

impl<St1, St2> Zip<St1, St2> where
St1: Stream,
St2: Stream,

source

pub fn get_ref(&self) -> (&St1, &St2)

Acquires a reference to the underlying streams that this combinator is pulling from.

source

pub fn get_mut(&mut self) -> (&mut St1, &mut St2)

Acquires a mutable reference to the underlying streams that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.

source

pub fn get_pin_mut(
self: Pin<&mut Zip<St1, St2>>
) -> (Pin<&mut St1>, Pin<&mut St2>)

Acquires a pinned mutable reference to the underlying streams that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this combinator.

source

pub fn into_inner(self) -> (St1, St2)

Consumes this combinator, returning the underlying streams.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
