Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§connection_count: AtomicUsize

Guage of active connections to the database server, this includes both connections that have belong to the pool, and connections currently owned by the application.

§connections_in_pool: AtomicUsize

Guage of active connections that currently belong to the pool.

§active_wait_requests: AtomicUsize

Guage of GetConn requests that are currently active.

§create_failed: AtomicUsize

Counter of connections that failed to be created.

§discarded_superfluous_connection: AtomicUsize

Counter of connections discarded due to pool constraints.

§discarded_unestablished_connection: AtomicUsize

Counter of connections discarded due to being closed upon return to the pool.

§dirty_connection_return: AtomicUsize

Counter of connections that have been returned to the pool dirty that needed to be cleaned (ie. open transactions, pending queries, etc).

§discarded_expired_connection: AtomicUsize

Counter of connections that have been discarded as they were expired by the pool constraints.

§resetting_connection: AtomicUsize

Counter of connections that have been reset.

§discarded_error_during_cleanup: AtomicUsize

Counter of connections that have been discarded as they returned an error during cleanup.

§connection_returned_to_pool: AtomicUsize

Counter of connections that have been returned to the pool.
