Redis-rs is a high level redis library for Rust. It provides convenient access
to all Redis functionality through a very flexible but low-level API. It
uses a customizable type conversion trait so that any operation can return
results in just the type you are expecting. This makes for a very pleasant
development experience.
The crate is called `redis` and you can depend on it via cargo:
```ini
[dependencies]
redis = "0.10.0"
```
Documentation on the library can be found at
[docs.rs/redis](https://docs.rs/redis).
**Note: redis-rs requires at least [Rust 1.26](https://blog.rust-lang.org/2018/05/10/Rust-1.26.html).**
## Basic Operation
To open a connection you need to create a client and then to fetch a
connection from it. In the future there will be a connection pool for
those, currently each connection is separate and not pooled.
Many commands are implemented through the `Commands` trait but manual
command creation is also possible.
```rust
extern crate redis;
use redis::Commands;
fn fetch_an_integer() -> redis::RedisResult<isize> {
// connect to redis
let client = redis::Client::open("redis://127.0.0.1/")?;
let con = client.get_connection()?;
// throw away the result, just make sure it does not fail
let _ : () = con.set("my_key", 42)?;
// read back the key and return it. Because the return value
// from the function is a result for integer this will automatically
// convert into one.
con.get("my_key")
}
```
