Redis-rs

let mut con = client.get_connection()?;
redis::cmd("SET").arg("my_key").arg(42).execute(&mut con);


Due to this, `transaction` has changed. The callback now also receives a mutable reference to the used connection.

Old code:

rust
let client = redis::Client::open("redis://127.0.0.1/").unwrap();
let con = client.get_connection().unwrap();
let key = "the_key";
let (new_val,) : (isize,) = redis::transaction(&con, &[key], |pipe| {
let old_val : isize = con.get(key)?;
pipe
.set(key, old_val + 1).ignore()
.get(key).query(&con)
})?;


New code:

rust
let client = redis::Client::open("redis://127.0.0.1/").unwrap();
let mut con = client.get_connection().unwrap();
let key = "the_key";
let (new_val,) : (isize,) = redis::transaction(&mut con, &[key], |con, pipe| {
let old_val : isize = con.get(key)?;
pipe
.set(key, old_val + 1).ignore()
.get(key).query(&con)
})?;


Remove `rustc-serialize` feature ([200](https://github.com/mitsuhiko/redis-rs/pull/200))

We removed serialization to/from JSON. The underlying library is deprecated for a long time.

Old code in `Cargo.toml`:


[dependencies.redis]

Note that this release fixes a small regression in async Redis Cluster handling of the `PING` command.
Based on updated response aggregation logic in [888](https://github.com/redis-rs/redis-rs/pull/888), it
will again return a single response instead of an array.

Features
* Add `key_type` command ([933](https://github.com/redis-rs/redis-rs/pull/933) bruaba)
* Async cluster: Group responses by response_policy. ([888](https://github.com/redis-rs/redis-rs/pull/888))

redis-0.23.0
This release adds the `cluster_async` module, which introduces async Redis Cluster support. The code therein is largely taken from Marwes's [redis-cluster-async crate](https://github.com/redis-rs/redis-cluster-async), which itself appears to have started from a sync Redis Cluster mplementation started by atuk721. In any case, thanks to Marwes and atuk721 for the great work, and we hope to keep development moving forward in `redis-rs`.

This release also adds support for Rustls, a long-sought feature. Thanks to rharish101 and LeoRowan for getting this in! Note that the `tls` and `async-std-tls-comp` features have been deprecated and replaced by `tls-native-tls` and `async-std-native-tls-comp`, respectively.

Though async Redis Cluster functionality for the time being has been kept as close to the originating crate as possible, previous users of
`redis-cluster-async` should note the following changes:
* Retries, while still configurable, can no longer be set to `None`/infinite retries
* Routing and slot parsing logic has been removed and merged with existing `redis-rs` functionality
* The client has been removed and superceded by common `ClusterClient`
* Renamed `Connection` to `ClusterConnection`
* Added support for reading from replicas
* Added support for insecure TLS
* Added support for setting both username and password

Breaking Changes
* Fix long-standing bug related to `AsyncIter`'s stream implementation in which polling the server
for additional data yielded broken data in most cases. Type bounds for `AsyncIter` have changed slightly,
making this a potentially breaking change. ([597](https://github.com/redis-rs/redis-rs/pull/597) roger)

Changes
* Update Rustls to v0.21.0 ([820](https://github.com/redis-rs/redis-rs/pull/820) rharish101)

* Commands: Add additional generic args for key arguments ([795](https://github.com/redis-rs/redis-rs/pull/795) MaxOhn)
* Add `mset` / deprecate `set_multiple` ([766](https://github.com/redis-rs/redis-rs/pull/766) randomairborne)
* More efficient interfaces for `MultiplexedConnection` and `ConnectionManager` ([811](https://github.com/redis-rs/redis-rs/pull/811) nihohit)
* Refactor / remove flaky test ([810](https://github.com/redis-rs/redis-rs/pull/810))
* `cluster_async`: rename `Connection` to `ClusterConnection`, `Pipeline` to `ClusterConnInner` ([808](https://github.com/redis-rs/redis-rs/pull/808))
* Support parsing IPV6 cluster nodes ([796](https://github.com/redis-rs/redis-rs/pull/796) socs)
* Common client for sync/async cluster connections ([798](https://github.com/redis-rs/redis-rs/pull/798))
* `cluster::ClusterConnection` underlying connection type is now generic (with existing type as default)
* Support `read_from_replicas` in cluster_async
* Set retries in `ClusterClientBuilder`
* Add mock tests for `cluster`
* cluster-async common slot parsing([793](https://github.com/redis-rs/redis-rs/pull/793))
* Support async-std in cluster_async module ([790](https://github.com/redis-rs/redis-rs/pull/790))
* Async-Cluster use same routing as Sync-Cluster ([789](https://github.com/redis-rs/redis-rs/pull/789))
* Add Async Cluster Support ([696](https://github.com/redis-rs/redis-rs/pull/696))
* Fix broken json-module tests ([786](https://github.com/redis-rs/redis-rs/pull/786))
