Module jsonrpc 

Content-Length framed JSON-RPC 2.0 codec.

This is the message framing used by JSON-RPC over stdio transports such as the Model Context Protocol (MCP): each message is prefixed with a Content-Length: N\r\n\r\n header followed by exactly N bytes of UTF-8 JSON body.

The framing codec (read_payload, write_message) is serializer agnostic — it operates on raw strings. The JSON-RPC 2.0 envelope builders (build_result_message, build_error_message, build_notification) are parameterized over a JsonRpcSerializer so this crate does not depend on any concrete JSON value type; the caller binds its own serializer.

Traits

JsonRpcSerializer

Abstraction over a JSON serializer so the JSON-RPC envelope builders do not depend on a concrete JSON value type.

Functions

build_error_message

build_result_message

Build a JSON-RPC 2.0 result message.

read_payload

Read a JSON-RPC payload from a buffered reader.

write_message

Write a Content-Length framed JSON-RPC message to a writer.
