Trait AppendContext 

pub trait AppendContext<R>: Context
where
    R: Context,
{
    type Appended: Context;

    // Required methods
    fn append_context(
        channels1: <Self as Context>::Endpoints,
        channels2: <R as Context>::Endpoints,
    ) -> <Self::Appended as Context>::Endpoints;
    fn split_context(
        channels: <Self::Appended as Context>::Endpoints,
    ) -> (<Self as Context>::Endpoints, <R as Context>::Endpoints);
}

Required Associated Types

type Appended: Context

Required Methods

fn append_context( channels1: <Self as Context>::Endpoints, channels2: <R as Context>::Endpoints, ) -> <Self::Appended as Context>::Endpoints

fn split_context( channels: <Self::Appended as Context>::Endpoints, ) -> (<Self as Context>::Endpoints, <R as Context>::Endpoints)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl<P, R, S> AppendContext<S> for (P, R)

where P: Slot, R: Context + AppendContext<S>, S: Context,

type Appended = (P, <R as AppendContext<S>>::Appended)

fn append_context( (p, r): (P::Endpoint, R::Endpoints), s: <S as Context>::Endpoints, ) -> (<P as Slot>::Endpoint, <R::Appended as Context>::Endpoints)

fn split_context( (p, r): (P::Endpoint, <R::Appended as Context>::Endpoints), ) -> (<(P, R) as Context>::Endpoints, <S as Context>::Endpoints)

impl<R: Context> AppendContext<R> for ()

type Appended = R

fn append_context( _: (), r: <R as Context>::Endpoints, ) -> <R as Context>::Endpoints
