Module faas 

Shared helpers for the serverless / function-as-a-service upstream plugins (azure-functions, openfunction, openwhisk).

These plugins all invoke an external FaaS endpoint and return its reply as the gateway response. The helpers here centralize the request-forwarding shape (method, headers, query, target URL) and the outbound-error → status mapping so each plugin only adds its own auth header and response handling.

Functions

classify_error

Maps an OutboundError to a client-facing (status, message) pair used by the FaaS plugins’ error ports.

forward_parts

Builds the forwarded request parts for a FaaS callout: the header list (client headers minus hop-by-hop, with Host overridden to the endpoint), the fully-qualified target URL (function_uri path plus the client’s query string), and the client’s HTTP method.

query_string 🔒

Encodes the request query parameters as a &-joined name=value string, sorted for stable output. Names and values are percent-encoded.

uri_encode 🔒

Percent-encodes per RFC 3986, keeping the unreserved set intact.
