Module seamless::handler [−][src]
Expand description
This module provides traits and structs that relate to the handler functions that we can pass to API routes.
Re-exports
pub use body::HandlerBody;pub use response::HandlerResponse;Modules
This contains the HandlerBody trait, which you can implement on a type
in order to allow it to be used at a parameter in a handler function which
can extract data from the request body. A couple of convenience types
(body::FromJson and body::FromBinary) are exposed which implement this trait.
This contains helpers around the body that you’ll need to provide as part
of an http::Request, mainly geared around allowing requests to be streamed
in if desired.
This module provides some functionality for creating a valid request body to send to Seamless as
part of an http::Request. Essentially, anything implementing AsyncRead + Send + Unpin can be
provided as a request body, but this module provides a Bytes struct which can easily convert a
Vec<u8> or [futures::Stream] into such a body.
This contains the HandlerResponse trait, which determines how to form an HTTP
response given some type. Implement this for types that you wish to be able to
return from handler functions.
Traits
Implement this for anything that you want to be able to pass into a request handler that doesn’t want to consume the body of the request. This is useful for implementing request guards which prevent the handler from being called unless specific conditions are met (for instance a user is logged in).
