Module version 

Version compatibility and rolling upgrade support.

This module provides version constants, compatibility checks, and a handshake protocol for multi-node clusters to detect incompatible version combinations before establishing connections.

Structs

VersionHandshake

Version handshake exchanged between nodes on initial connection.

Constants

CURRENT_VERSION

Current version of this build, taken from Cargo.toml at compile time.

MIN_COMPATIBLE_VERSION

Minimum compatible version: nodes running this version or newer (with the same major) are accepted into the cluster.

Functions

is_compatible

Returns true when peer_version is considered compatible with this node.
