Structs

ConnectionCheckedInEvent	Event emitted when a connection is checked back into a connection pool.

ConnectionCheckoutFailedEvent	Event emitted when a thread is unable to check out a connection.
ConnectionCheckoutStartedEvent	Event emitted when a thread begins checking out a connection to use for an operation.
ConnectionClosedEvent	Event emitted when a connection is closed.
ConnectionCreatedEvent	Event emitted when a connection is created.
ConnectionPoolOptions	Contains the options for creating a connection pool. While these options are specified at the client-level, `ConnectionPoolOptions` is exposed for the purpose of CMAP event handling.

PoolClearedEvent	Event emitted when a connection pool is cleared.
PoolClosedEvent	Event emitted when a connection pool is cleared.
PoolCreatedEvent	Event emitted when a connection pool is created.

ConnectionCheckoutFailedReason	The reasons a connection may not be able to be checked out.

Applications can implement this trait to specify custom logic to run on each CMAP event sent by the driver.
