//! The official Rust implementation of [gRPC], a high performance, open source,
//! universal RPC framework.
//!
//! > NOTE: This version is a preview and not recommended for any production
//! > use.  All APIs are unstable.  Proceed at your own risk.

//!
//! # Feature Flags
//!
//! The only currently-supported feature flags are the defaults.
//!
//! # Modules
//!
//! * [`client`] - Creating and working with gRPC client-side channels
//! * [`credentials`] - Securing connections and providing access tokens
//! * [`metadata`] - Data sent with all RPCs typically used by interceptors
//! * [`core`] - Common types shared between clients and servers
//! * [`attributes`] - Generic key/value storage used by gRPC plugins
