Change Log

v0.5.0-alpha.2 - 2019-11-27

Changed

  • Upgraded bytes to 0.5.
  • Upgraded tokio to 0.2.
  • The TLS interface uses a trait to obtain channel binding information rather than returning it after the handshake.
  • Changed the value of the timezone property from GMT to UTC.
  • Returned Stream implementations are now !Unpin.

Added

  • Added support for uuid 0.8.
  • Added the column to Row::try_get errors.

v0.5.0-alpha.1 - 2019-10-14

Changed

  • The library now uses std::futures::Future and async/await syntax.
  • Most methods now take &self rather than &mut self.
  • The transaction API has changed to more closely resemble the synchronous API and is significantly more ergonomic.
  • Methods now take &[&(dyn ToSql + Sync)] rather than &[&dyn ToSql] to allow futures to be Send.
  • Methods are now "normal" async functions that no longer do work up-front.
  • Statements are no longer required to be prepared explicitly before use. Methods taking &Statement can now also take &str, and will internally prepare the statement.
  • ToSql now serializes its value into a BytesMut rather than Vec<u8>.
  • Methods that previously returned Streams now return Vec<T>. New *_raw methods still provide a Stream interface.

Added

  • Added the channel_binding=disable/allow/require configuration to control use of channel binding.
  • Added the Client::query_one method to cover the common case of a query that returns exactly one row.

v0.4.0-rc.3 - 2019-06-29

Fixed

  • Significantly improved the performance of query and copy_in.

Changed

  • The items of the stream passed to copy_in must be 'static.

v0.4.0-rc.2 - 2019-03-05

Fixed

  • Fixed Cargo features to actually enable the functionality they claim to.

v0.4.0-rc.1 - 2019-03-05

Changed

  • The client API has been significantly overhauled. It now resembles hyper's, with separate Connection and Client objects. See the crate-level documentation for more details.
  • The TLS connection mode (e.g. prefer) is now part of the connection configuration rather than being passed in separately.
  • The Cargo features enabling ToSql and FromSql implementations for external crates are now versioned. For example, with-uuid is now with-uuid-0_7. This enables us to add support for new major versions of the crates in parallel without breaking backwards compatibility.
  • Upgraded from tokio-core to tokio.

Added

  • Connection string configuration now more fully mirrors libpq's syntax, and supports both URL-style and key-value style strings.
  • FromSql implementations can now borrow from the data buffer. In particular, this means that you can deserialize values as &str. The FromSqlOwned trait can be used as a bound to restrict code to deserializing owned values.
  • Added support for channel binding with SCRAM authentication.
  • Added multi-host support in connection configuration.
  • The client now supports query pipelining, which can be used as a latency hiding measure.
  • While the crate uses tokio by default, the base API can be used with any asynchronous stream type on any reactor.
  • Added support for simple query requests returning row data.

Removed

  • The with-openssl feature has been removed. Use the tokio-postgres-openssl crate instead.
  • The with-rustc_serialize and with-time features have been removed. Use serde and SystemTime or chrono instead.
