Implementations§

Source§

impl<S, T> Chain<S, T>
where S: AsyncDecode,

Source

pub fn new(first: S, second: T) -> Chain<S, T>

Trait Implementations§

Source§

impl<S, T> AsyncDecode for Chain<S, T>
where S: AsyncDecode, T: AsyncDecode<Error = S::Error>,

Source§

type Item = (<S as AsyncDecode>::Item, <T as AsyncDecode>::Item)
