Trait RequestHandler 

pub trait RequestHandler {
    // 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 request body as it is polled by the inner service.

All methods default to no-ops, so implementors only override the events they care about. The unit type () has a blanket impl with every method a no-op; use type RequestHandler = (); when only the response side is interesting.

Provided Methods

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

where B: Buf,

Called once per data frame yielded by the request body.

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

Called at most once when the request body stream ends.

trailers is Some if the final frame was a trailers frame, otherwise None.

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

where E: Display + 'static,

Called when polling the request 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.
