# [−] Trait actix_web::actix::actix::dev::ResponseChannel

    pub trait ResponseChannel<M>: 'static where
        M: Message, {
        fn is_canceled(&self) -> bool;
        fn send(self, response: <M as Message>::Result);
    }

Trait defines message response channel

## Required Methods

## Implementations on Foreign Types

###

`impl<M> ResponseChannel<M> for Sender<<M as Message>::Result> where M: 'static + Message, <M as Message>::Result: Send,`

####

`fn is_canceled(&self) -> bool` |

####

`fn send(self, response: <M as Message>::Result)` |

###

`impl<M> ResponseChannel<M> for () where M: 'static + Message,`

####

`fn is_canceled(&self) -> bool` |

####

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
