Change Log

v0.5.4- 2020-05-01

Added

• Added Transaction::savepoint, which can be used to create a savepoint with a custom name.

v0.5.3 - 2020-03-05

Added

• Added Debug implementations for Client, Row, and Column.
• Added time 0.2 support.

v0.5.2 - 2020-01-31

Fixed

• Notice messages sent during the initial connection process are now collected and returned first from Connection::poll_message.

Deprecated

• Deprecated Client::cancel_query and Client::cancel_query_raw in favor of Client::cancel_token.

Added

• Added Client::build_transaction to allow configuration of various transaction options.
• Added Client::cancel_token, which returns a separate owned object that can be used to cancel queries.
• Added accessors for Config fields.
• Added a GenericClient trait implemented for Client and Transaction and covering shared functionality.

v0.5.1 - 2019-12-25

Fixed

• Removed some stray println!s from copy_out internals.

v0.5.0 - 2019-12-23

Changed

• Client::copy_in now returns a Sink rather than taking in a Stream.
• CopyStream has been renamed to CopyOutStream.
• Client::copy_in and Client::copy_out no longer take query parameters as PostgreSQL doesn't support parameters in COPY queries.
• TargetSessionAttrs, SslMode, and ChannelBinding are now true non-exhaustive enums.

Added

• Added Client::query_opt for queries expected to return zero or one rows.
• Added binary copy format support to the binary_copy module.
• Added back query logging.

Removed

• Removed uuid 0.7 support.

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.
