Struct ConnectionManager 

pub struct ConnectionManager { /* private fields */ }

Connection manager for ClickHouse clients that implements BB8’s ManageConnection trait.

This manager handles creation, validation, and recycling of ClickHouse client connections. It uses a ConnectionBuilder to configure new clients and periodically executes select 1; to verify that clients are still valid.
