Module rpc 

RPC binding wire types.

Both the server binding (cratestack-axum::rpc) and every generated client (cratestack-client-rust, the TS / Dart generators) agree on these shapes. They live in cratestack-core so clients can depend on a single source of truth without pulling in axum.

Server-only helpers (codec-aware encoding, axum response post-processing, batch frame assembly) stay in cratestack-axum::rpc. This module owns only the wire shapes and the CoolError → gRPC-style code mapping.

Structs

RpcErrorBody

Wire shape of a single error returned by an RPC call. Maps from CoolError via rpc_code + CoolError::public_message.

RpcRequest

Wire shape of a single batch request frame.

RpcResponseFrame

Wire shape of a single batch response frame.

Constants

RPC_BATCH_PATH

Mount path for batched RPC calls. Body is a codec-encoded sequence of RpcRequest frames.

RPC_UNARY_PATH

Mount path for unary RPC calls. The trailing segment is the percent-decoded op id, e.g. POST /rpc/model.User.list.

Functions

cool_error_code_to_rpc_code

Map a CoolErrorResponse.code string (screaming-snake, REST- binding vocabulary) to the stable gRPC-style code the RPC binding emits.

rpc_code

Map a CoolError to its stable RPC code (gRPC-style snake_case).
