Define Redis built-in commands in a set of traits

§Built-in commands

Because Redis offers hundreds of commands, in rustis commands have been split in several traits that gather commands by groups, most of the time, groups describe in Redis official documentation.

Depending on the group of commands, traits will be implemented by Client, Pipeline, Transaction or some of these structs.

These is the list of existing command traits:

BitmapCommands: Bitmaps & Bitfields
BlockingCommands: Commands that block the connection until the Redis server has a new element to send. This trait is implemented only by the Client struct.
ClusterCommands: Redis cluster
ConnectionCommands: Connection management like authentication or RESP version management
GenericCommands: Generic commands like deleting, renaming or expiring keys
GeoCommands: Geospatial indices
HashCommands: Hashes
HyperLogLogCommands: HyperLogLog
ListCommands: Lists
PubSubCommands: Pub/Sub
ScriptingCommands: Scripts & Functions
SentinelCommands: Sentinel
ServerCommands: Server management like Access Control Lists or monitoring
SetCommands: Sets
SortedSetCommands: Sorted sets
StreamCommands: Streams
StringCommands: Strings
VectorSetCommands: Vector sets
TransactionCommands: Transactions
BloomCommands: Bloom filters
CuckooCommands: Cuckoo filters
CountMinSketchCommands: Count min-sketch
JsonCommands: RedisJson
SearchCommands: RedisSearch
TDigestCommands: T-Digest
TimeSeriesCommands: Time Series
TopKCommands: Top-K

§Example

To use a command, simply add the related trait to your use declerations and call the related associated function directly to a client, pipeline, transaction instance.

Commands can be directly awaited or forgotten.

use rustis::{
    client::{Client, ClientPreparedCommand},
    commands::{ListCommands, SortedSetCommands, ZAddOptions},
    Result,
};

#[cfg_attr(feature = "tokio-runtime", tokio::main)]
#[cfg_attr(feature = "async-std-runtime", async_std::main)]
async fn main() -> Result<()> {
    let client = Client::connect("127.0.0.1:6379").await?;

    // Send & await ListCommands::lpush command
    let _size = client.lpush("mylist", ["element1", "element2"]).await?;

    // Send & forget SortedSetCommands::zadd command
    let _size = client.zadd(
        "mySortedSet",
        [(1.0, "member1"), (2.0, "member2")],
        ZAddOptions::default()
    ).forget();

    Ok(())
}
