Types

HTTP methods

base::types::http::Method is a bitflag set, so a route can carry several methods in one value:

GET POST PATCH PUT DELETE HEAD OPTIONS CONNECT TRACE

Parsed case-insensitively from a string via FromStr.

ABI types

The Omni ABI (base::types::Types) is the vocabulary handlers speak:

Type	Meaning
OmniContext	The per-request context; a handler's required first parameter.
OmniRequest	The incoming request.
OmniResponse	The response.
OmniHeader	A header value.
OmniBody	A request or response body.

base::abi::is_ctx recognizes the context type ("Omni.Context") during discovery.

Route model

• RouteSeg - a path segment, either Static(name) or Dynamic(name) (a :param).
• RouteFlags - DB, Ctx, Hdr, Bdy, Dyn, Hot: what a handler touches, used to specialize generated code.
• Node - a discovered route node: Endpoint(datum, Method) or Middleware(datum). NodeDatum holds the source file, function name, params, returns, flags, and the parsed AST.
