1//! # Gantry streaming protocol
2//!
3//! This module contains data types and traits for use with Gantry's module streaming
4//! functionality. Gantry separates the streaming of a module's raw bytes from the management
5//! of a module's metadata. The following operations are available for streaming:
6//! * `stream_put` - Send the raw bytes for a module to Gantry, corresponding to a specific public key+revision pair
7//! * `stream_get` - Retrieve the raw bytes for a module to Gantry, corresponding to a specific public key+revision pair
