ExMCP.Client.StateMachine (ex_mcp v0.9.2)

GenStateMachine implementation for ExMCP.Client.

This module formalizes the client's state transitions and reduces complexity by using state-specific data structures instead of a single monolithic state.

States

:disconnected - No active connection
:connecting - Transport connection being established
:handshaking - MCP protocol handshake in progress
:ready - Connected and ready to handle requests
:reconnecting - Connection lost, attempting to reconnect

State Transitions

disconnected -> connecting -> handshaking -> ready
