}

HTTP context encapsulating the request, response, and service provider for the duration of a single HTTP request.

Extends IClaimsExt so middleware can store/retrieve auth claims.

Analogous to ASP.NET Core’s HttpContext.

Required Methods

fn request(&self) -> &dyn IHttpRequest

fn request_mut(&mut self) -> &mut dyn IHttpRequest

fn response(&self) -> &dyn IHttpResponse

fn response_mut(&mut self) -> &mut dyn IHttpResponse

Provided Methods

fn take_early_error(&mut self) -> Option<Error>

Take a request rejection recorded while the context was built.

The host records failures it can detect from the request line alone — currently an oversized declared Content-Length — instead of writing a response eagerly. The request then still travels through the middleware pipeline (CORS, security headers, access log, metrics, rate limiting) and the innermost handler turns the value into the normal error response. A context without such a record returns None.

fn dispatch_runtime(&self) -> Option<&Arc<DispatchRuntime>>

DI handles of the host that dispatched this request.

Endpoint adapters use this to build the Mediator over the host’s service provider and handler registry. Contexts created by tests or alternative hosts return None; dispatching an endpoint through such a context is a programming error and is reported as Error::Internal.

fn trace_id(&self) -> Option<&str>

The trace id assigned to this request, if any.

Set by the tracing middleware (webx_host::RequestTracing) before the endpoint runs, so the binder, the handler and the response header all agree on one value. Handlers read it through RequestContext::trace_id, which the endpoint adapter scopes from this value.

Returns None for alternative hosts that never assign a trace id and for requests that did not pass the tracing middleware.

fn set_trace_id(&mut self, _trace_id: &str)

Record the trace id for this request.

Called by the tracing middleware’s invoke, which then echoes the same value in the x-trace-id response header. The default is a no-op so existing/alternative context implementations keep compiling; such hosts simply have no trace id.

Dyn Compatibility

This trait is dyn compatible.

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