Struct DBConnectionManager 

pub struct DBConnectionManager<D>
where
    D: Driver,
{ /* private fields */ }

The Manager that backs every Tank connection pool.

A manager holds the Driver and the database URL; it knows how to open new connections on demand and how to validate recycled ones. You do not need to construct or interact with this type directly, it is created internally by Driver::connect_pool.
