Overview

Detects direct calls to ‘Legion::Transport::Connection` methods and suggests using the `transport_*` helpers instead.

Examples:

# bad
Legion::Transport::Connection.session_open?
Legion::Transport::Connection.channel_open?
Legion::Transport::Connection.lite_mode?
Legion::Transport::Connection.channel

# good
transport_session_open?
transport_channel_open?
transport_lite_mode?
transport_channel
