Trait actix_web::Responder

pub trait Responder {
    type Item: Into<Reply>;
    type Error: Into<Error>;
    fn respond_to(self, req: HttpRequest) -> Result<Self::Item, Self::Error>;
}

Trait implemented by types that generate responses for clients.

Types that implement this trait can be used as the return type of a handler.

Associated Types

type Item: Into<Reply>

The associated item which can be returned.

type Error: Into<Error>

The associated error which can be returned.

Required Methods

fn respond_to(self, req: HttpRequest) -> Result<Self::Item, Self::Error>

Convert itself to Reply or Error.
