//! This module provides base primitives for encoding and decoding u32 values.
//!
//! It mostly centralizes the knowledge that the protocol uses little-endian
//! representation for u32 values.

/// Length of an encoded 32-bit integer in bytes.

/// Returns the byte representatio of the given integer value.

  value.to_le_bytes()
}

/// Returns the integer value corresponding to the given bytes.
