Trait ResponseHandler 

pub trait ResponseHandler {
    // Required methods
    fn on_response(&mut self, response: &Parts);
    fn on_service_error<E>(&mut self, error: &E)
       where E: Display + 'static;

    // Provided methods
    fn on_body_chunk<B>(&mut self, _chunk: &B)
       where B: Buf { ... }
    fn on_end_of_stream(&mut self, _trailers: Option<&HeaderMap>) { ... }
    fn on_body_error<E>(&mut self, _error: &E)
       where E: Display + 'static { ... }
}

Observes the response as seen by the caller: the response parts, the response body, and the service-level error that occurs if the inner service’s future resolves to Err before any response is produced.

Body-level methods default to no-ops.

Required Methods

fn on_response(&mut self, response: &Parts)

Called exactly once when the inner service produces a response.

fn on_service_error<E>(&mut self, error: &E)

where E: Display + 'static,

Called when the inner service’s future resolves to Err (no response is produced). Response body errors are reported separately through Self::on_body_error.

Provided Methods

fn on_body_chunk<B>(&mut self, _chunk: &B)

where B: Buf,

Called once per data frame yielded by the response body.

fn on_end_of_stream(&mut self, _trailers: Option<&HeaderMap>)

Called at most once when the response body stream ends.

fn on_body_error<E>(&mut self, _error: &E)

where E: Display + 'static,

Called when polling the response body yields an error.

Dyn Compatibility

This trait is not dyn compatible.

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