Expand description

Implements common redis commands for connection like objects.

This allows you to send commands straight to a connection or client. It is also implemented for redis results of clients which makes for very convenient access in some basic cases.

This allows you to use nicer syntax for some common operations. For instance this code:

    let client = redis::Client::open("redis://127.0.0.1/")?;
    let mut con = client.get_connection()?;
    redis::cmd("SET").arg("my_key").arg(42).exec(&mut con).unwrap();
    assert_eq!(redis::cmd("GET").arg("my_key").query(&mut con), Ok(42));

Will become this:

    use redis::Commands;
    let client = redis::Client::open("redis://127.0.0.1/")?;
    let mut con = client.get_connection()?;
    let _: () = con.set("my_key", 42)?;
    assert_eq!(con.get("my_key"), Ok(42));

#### fn geo_pos<'a, K: ToSingleRedisArg, M: ToRedisArgs, RV: FromRedisValue>( &mut self, key: K, members: M, ) -> RedisResult<RV>

    use redis::geo::Coord;

    fn get_position(con: &mut redis::Connection) {
        let x: RedisResult<Vec<Vec<f64>>> = con.geo_pos("my_gis", &["Palermo", "Catania"]);
        // x is [ [ 13.361389, 38.115556 ], [ 15.087269, 37.502669 ] ];

        let x: Vec<Coord<f64>> = con.geo_pos("my_gis", "Palermo").unwrap();
        // x[0].longitude is 13.361389
        // x[0].latitude is 38.115556
    }

Available on crate feature `streams` only.

This command is used for creating a consumer `group`. It expects the stream key to already exist. Otherwise, use `xgroup_create_mkstream` if it doesn’t. The `id` is the starting message id all consumers should read from. Use `$` If you want all consumers to read from the last message added to stream.

## Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
