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).execute(&mut con);
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()?;
con.set("my_key", 42)?;
assert_eq!(con.get("my_key"), Ok(42));

    &mut self,
    key: K,
    member1: M1,
    member2: M2,
    unit: Unit
) -> RedisResult<RV>

Return the distance between two members in the geospatial index represented by the sorted set.

If one or both the members are missing, the command returns NULL, so it may be convenient to parse its response as either Option<f64> or Option<String>.

Example

use redis::{Commands, RedisResult};
use redis::geo::Unit;

fn get_dists(con: &mut redis::Connection) {
    let x: RedisResult<f64> = con.geo_dist(
        "my_gis",
        "Palermo",
        "Catania",
        Unit::Kilometers
    );
    // x is Ok(166.2742)

    let x: RedisResult<Option<f64>> = con.geo_dist(
        "my_gis",

}

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

Return valid Geohash strings representing the position of one or more members of the geospatial index represented by the sorted set at key.

Example

use redis::{Commands, RedisResult};

fn get_hash(con: &mut redis::Connection) {
    let x: RedisResult<Vec<String>> = con.geo_hash("my_gis", "Palermo");
    // x is vec!["sqc8b49rny0"]

    let x: RedisResult<Vec<String>> = con.geo_hash("my_gis", &["Palermo", "Catania"]);
    // x is vec!["sqc8b49rny0", "sqdtr74hyu0"]
}

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

Return the positions of all the specified members of the geospatial index represented by the sorted set at key.

Every position is a pair of (longitude, latitude). redis::geo::Coord can be used to convert these value in a struct.

Example

use redis::{Commands, RedisResult};
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
}

    unit: Unit,
    options: RadiusOptions
) -> RedisResult<RV>

Return the members of a sorted set populated with geospatial information using geo_add, which are within the borders of the area specified with the center location and the maximum distance from the center (the radius).

Every item in the result can be read with redis::geo::RadiusSearchResult, which support the multiple formats returned by GEORADIUS.

use redis::{Commands, RedisResult};
use redis::geo::{RadiusOptions, RadiusSearchResult, RadiusOrder, Unit};

fn radius(con: &mut redis::Connection) -> Vec<RadiusSearchResult> {
    let opts = RadiusOptions::default().with_dist().order(RadiusOrder::Asc);

    consumer: C,
    min_idle_time: MIT,
    ids: &'a [ID]
) -> RedisResult<RV>

fn xpending<'a, K: ToRedisArgs, G: ToRedisArgs, RV: FromRedisValue>(
    &mut self,
    key: K,
    group: G
) -> RedisResult<RV>

This is a basic version of making XPENDING command calls which only passes a stream key and consumer group and it returns details about which consumers have pending messages that haven’t been acked.

You can use this method along with xclaim or xclaim_options for determining which messages need to be retried.

Take note of the StreamPendingReply return type.

XPENDING <key> <group> [<start> <stop> <count> [<consumer>]]

    group: G,
    start: S,
    end: E,
    count: C
) -> RedisResult<RV>

This XPENDING version returns a list of all messages over the range. You can use this for paginating pending messages (but without the message HashMap).

Start and end follow the same rules xrange args. Set start to - and end to + for the entire stream.

Start and end follow the same rules xrange args. Set start to - and end to + for the entire stream.

Take note of the StreamPendingCountReply return type.

XPENDING <key> <group> <start> <stop> <count> <consumer>

fn xrange<'a, K: ToRedisArgs, S: ToRedisArgs, E: ToRedisArgs, RV: FromRedisValue>(
