Expand description

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.

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.
§max_idle_time: Option<Duration>

Connections that have been ready for usage in the pool for longer than max_idle_time will not be used.

The default is that connections will not be closed due to being idle.

§max_pool_size: Option<u32>

The maximum number of connections that the pool can have at a given time. This includes connections which are currently checked out of the pool.

The default is 10.

§min_pool_size: Option<u32>

The minimum number of connections that the pool can have at a given time. This includes connections which are currently checked out of the pool. If fewer than min_pool_size connections are in the pool, connections will be added to the pool in the background.

The default is that no minimum is enforced
