Changed

  • Upgraded parking_lot.

0.8.9 - 2020-06-30

Changed

  • Upgraded parking_lot.

0.8.7 - 2019-11-25

Changed

  • Upgraded parking_lot.

0.8.6 - 2019-10-19

Added

  • Added the ability to associate arbitrary data with pooled connections.

0.8.5 - 2019-06-06

Changed

  • Upgraded parking_lot.

0.8.4 - 2019-04-01

Added

  • Added a HandleEvent trait used to listen for various events from the pool for monitoring purposes.

Changed

  • Switched from standard library synchronization primitives to parking_lot.

0.8.3 - 2018-11-03

Fixed

  • The set of idle connections is now treated as a stack rather than a queue. The old behavior interacted poorly with configurations that allowed the pool size to shrink when mostly idle.

0.8.2 - 2017-12-24

Changed

  • Upgraded from log 0.3 to 0.4.

0.8.1 - 2017-10-28

Fixed

  • Fixed the example in the README.

0.8.0 - 2017-10-26

Changed

  • Pool configuration has changed. Rather than constructing a Config and passing it to the Pool constructor, you now configure a Builder which then directly constructs the pool:

    // In 0.7.x
let config = Config::builder()
    .min_idle(3)
    .build();
let pool = Pool::new(config, manager)?;

// In 0.8.x
let pool = Pool::builder()
    .min_idle(3)
    .build(manager)?;

  • The Pool::new method can be used to construct a Pool with default settings:

    // In 0.7.x
let config = Config::default();
let pool = Pool::new(config, manager)?;

// In 0.8.x
let pool = Pool::new(manager)?;

  • The initialization_fail_fast configuration option has been replaced with separate Builder::build and Builder::build_unchecked methods. The second returns a Pool directly without wrapping it in a Result, and does not check that connections are being successfully opened:

    // In 0.7.x
let config = Config::builder()
    .initialization_fail_fast(false)
    .build();
let pool = Pool::new(config, manager).unwrap();

// In 0.8.x
let pool = Pool::builder().build_unchecked(manager);

  • The InitializationError and GetTimeout error types have been merged into a unified Error type.

  • The Pool::config method has been replaced with accessor methods on Pool to directly access configuration, such as Pool::min_idle.

  • The scheduled_thread_pool crate has been upgraded from 0.1 to 0.2.

Removed

  • The deprecated Builder::num_threads method has been removed. Construct a ScheduledThreadPool and set it via Builder::thread_pool instead.
