Module graphql 

GraphQL over HTTP (GraphQL-over-HTTP draft) on hyper. Rust owns request parsing, media-type negotiation, validation against the schema, introspection and execution; the handler owns the data behind every query and mutation.

Modules

actions

engine

GraphQL documents, schema, introspection and execution on apollo-compiler. Rust parses and validates every request against the configured SDL, answers introspection itself and runs the spec’s execution (result coercion, null propagation, error paths) over the data the handler supplies, so the response always matches the query that was asked.

ws

GraphQL over WebSocket, graphql-transport-ws (the graphql-ws protocol): connection init/ack, ping/pong, subscribe/next/error/complete, with the protocol’s close codes. Rust owns the lifecycle, ids and execution; the handler supplies each subscription’s events, either in its first answer or later through the connection’s peer handle.

Functions

negotiate

Pick the response media type from Accept: no header means application/json (the spec’s legacy rule); otherwise the acceptable type with the highest q, an exact type beating a wildcard, and None (406) when neither type is acceptable.
