foundation_connectrpc 0.0.1

//! `foundation_connectrpc` — ConnectRPC for the EWE platform.
//!
//! An independent Rust port of the Connect protocol (connect-go is the design
//! reference), built on the platform's foundation crates: `foundation_errstacks`
//! for the error model, `foundation_netio` for HTTP/wire types, and valtron for
//! execution.
//!
//! This crate is being built feature-by-feature (see `specifications/41-connectrpc`).
//! The first landed piece is the protocol-agnostic **error model** (Decision 03):
//! see [`error`].

// Cross-platform modules (native + wasm).
pub mod shared;

// Native-only modules (TCP server, h2/h3 transports).
#[cfg(not(target_family = "wasm"))]
pub mod native;

// Proto code generation (Decision 10 Modes 1–2) lives in the build-time
// companion crate `foundation_connectrpc_codegen` (the tonic/tonic-build split)
// — add it under `[build-dependencies]`. Code-first generation (Mode 3) is the
// `service!`/`generate!` proc-macros re-exported below and stays in-crate.

/// Re-export of the `buffa` protobuf crate as `foundation_connectrpc::buffa`.
///
/// Proto message types need a `buffa::Message` impl (normally emitted by
/// codegen; there is no derive). Hand-writing one — or working with buffa
/// messages directly — otherwise means adding a matching `buffa` dependency and
/// keeping its version in lockstep with ours. Re-exporting it here means a
/// consumer reaches the whole authoring surface through this crate:
/// `foundation_connectrpc::buffa::{Message, DefaultInstance, SizeCache}`,
/// `::buffa::encoding::{Tag, WireType, encode_varint, …}`, and even
/// `::buffa::bytes::{Buf, BufMut}` (buffa re-exports `bytes`). Pure-JSON /
/// code-first `codecs(json)` services need none of this — `JsonCodec` is bounded
/// on serde alone.
