//! gRPC server support for acton-service
//!
//! This module provides gRPC server functionality that can run alongside HTTP services.
//! It supports both single-port (HTTP + gRPC multiplexed) and dual-port modes.
//!
//! ## Middleware and Interceptors
//!
//! The gRPC implementation provides middleware parity with HTTP:
//! - **Request ID**: Automatic generation and propagation
//! - **Tracing**: OpenTelemetry integration with proper span context
//! - **Authentication**: PASETO (default) or JWT token validation via interceptors
//! - **Rate Limiting**: Governor-based rate limiting (when `governor` feature is enabled)
//!
//! ## Example
//!
//! ```ignore
//! use acton_service::grpc::interceptors::{request_id_interceptor, paseto_auth_interceptor};
//! use acton_service::grpc::middleware::GrpcTracingLayer;
//! use acton_service::middleware::PasetoAuth;
//! use std::sync::Arc;
//! use tonic::transport::Server;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! // Create PASETO auth
//! let paseto_auth = Arc::new(PasetoAuth::new(&config.token.unwrap())?);
//!
//! // Build gRPC service with interceptors
//! let service = MyServiceServer::with_interceptor(
//!     service_impl,
//!     move |req| {
//!         let req = request_id_interceptor(req)?;
//!         paseto_auth_interceptor(paseto_auth.clone())(req)
//!     }
//! );
//!
//! // Serve
//! Server::builder()
//!     .layer(GrpcTracingLayer)
//!     .add_service(service)
//!     .serve(addr)
//!     .await?;
//! # Ok(())
//! # }
//! ```
