Module metadata 

HTTP → gRPC metadata, trace-context, and deadline propagation.

Converts relevant HTTP headers into gRPC MetadataMap entries for upstream calls (forwarded headers are configurable via YAML), propagates W3C trace-context across the boundary, and carries a client deadline through as the upstream call timeout.

Structs

InvalidForwardedHeader

A forwarded request header whose value gRPC metadata cannot carry.

Functions

apply_request_deadline

Apply a client-supplied deadline to the upstream gRPC call.

http_headers_to_grpc_metadataDeprecated

Extract HTTP headers into a gRPC MetadataMap, forwarding every value as it arrived, including one gRPC metadata cannot carry.

try_http_headers_to_grpc_metadata

Extract HTTP headers into a gRPC MetadataMap, or refuse the request.
