HttpRequestLayer context interface

Required Associated Constants

const INSPECT_HEADERS: &'static [&'static HeaderName]

Specifies list of headers you want to inspect via http.headers attribute

Provided Methods

fn extract_client_ip(&self, span: &Span, parts: &Parts) -> Option<IpAddr>

Defines way to extract IpAddr from parts

Defaults to always return None

fn on_request<T>(&self, span: &Span, request: &Request<T>)

Callback to be called on incoming request

Defaults to be noop

fn on_response_ok<T>(&self, span: &Span, response: &mut Response<T>)

Callback to be called when successful response is returned

Defaults to be noop

fn on_response_error(&self, span: &Span, error: &impl Error)

Callback to be called when error is returned instead of response

Defaults to be noop

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.
