Trait ContextLens 

pub trait ContextLens<C, A1, A2>: Send + 'static
where
    C: Context,
    A1: Slot,
    A2: Slot,
{
    type Deleted: Context;
    type Target: Context;

    // Required methods
    fn extract_source(
        channels: C::Endpoints,
    ) -> (A1::Endpoint, <Self::Deleted as Context>::Endpoints);
    fn insert_target(
        receiver: A2::Endpoint,
        channels: <Self::Deleted as Context>::Endpoints,
    ) -> <Self::Target as Context>::Endpoints;
}

Required Associated Types

type Deleted: Context

type Target: Context

Required Methods

fn extract_source( channels: C::Endpoints, ) -> (A1::Endpoint, <Self::Deleted as Context>::Endpoints)

fn insert_target( receiver: A2::Endpoint, channels: <Self::Deleted as Context>::Endpoints, ) -> <Self::Target as Context>::Endpoints

Dyn Compatibility

This trait is not dyn compatible.

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