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", so this trait is not object safe.
