Crate id_effect_rpc 

RPC-style HTTP helpers for id_effect Axum hosts — Phase D (@effect/rpc-shaped boundaries).

Full stack (D3)

• protocol — tagged wire request/response types
• serialization — JSON + id_effect::schema encode/decode
• registry — RpcGroup of typed handlers
• server — RpcServer Axum dispatch (POST /rpc)
• client — RpcClient remote calls via id_effect_platform::http::HttpClient
• stream — NDJSON stream RPC responses

Edge helpers (D2)

• RpcError — JSON envelope + status + IntoResponse
• correlation — x-correlation-id propagation
• codegen — service metadata and Rust trait stub emission
• openapi — OpenAPI 3.0 JSON/YAML emission from route metadata
• span — tracing span helpers compatible with OpenTelemetry layers
• versioning — API version negotiation middleware

Pair with id_effect_axum::json (decode_json_schema, JsonSchemaError) for per-route JSON validation (see the mdBook Axum host chapter).

Modules

client

RPC HTTP client — call remote tagged methods as Effect (RpcClient parity).

codegen

RPC service metadata and Rust trait stub emission (Phase D3 spike).

correlation

Correlation id helpers for RPC-style HTTP (x-correlation-id).

error

RpcError — structured JSON body + HTTP status + Axum IntoResponse.

openapi

OpenAPI 3.0 document emission from RPC / HTTP route metadata.

protocol

Tagged RPC wire messages for the HTTP+JSON protocol (@effect/rpc-shaped).

registry

RPC method registry — [] of tagged handlers ( [] parity).

serialization

JSON serialization and id_effect::schema bridging for RPC wire messages.

server

RPC HTTP server — mount tagged dispatch on Axum (RpcServer.layer parity).

span

Tracing helpers for RPC-shaped HTTP handlers.

stream

NDJSON streaming RPC responses (stream methods at the HTTP edge).

versioning

API version negotiation for RPC-shaped Axum routes.

Structs

RpcEnvelope

Wire body returned for structured RPC errors.

Enums

RpcErrorCode

Coarse error category for HTTP APIs (paired with an HTTP status in crate::RpcError).
