Module hset

Abstraction of HSET command.

For general information about this command, see the Redis documentation.

Using command object

use embedded_redis::commands::hset::HashSetCommand;
let mut stack = Stack::default();
let clock = StandardClock::default();

let mut connection_handler = ConnectionHandler::resp2(SocketAddr::from_str("127.0.0.1:6379").unwrap());
let client = connection_handler.connect(&mut stack, Some(&clock)).unwrap();

let command = HashSetCommand::new("my_hash", "color", "green");
let response = client.send(command).unwrap().wait().unwrap();

// Returns the number of added fields
assert_eq!(1, response)

Setting multiple fields at once

let command = HashSetCommand::multiple("my_hash".into(), [
    ("color".into(), "green".into()),
    ("material".into(), "stone".into())
]);
let response = client.send(command).unwrap().wait().unwrap();

// Returns the number of added fields
assert_eq!(2, response)

Shorthand

Client provides a shorthand method for this command.

// Using &str arguments
let _ = client.hset("hash", "field", "value");

// Using String arguments
let _ = client.hset("hash".to_string(), "field".to_string(), "value".to_string());

// Using Bytes arguments
let _ = client.hset(Bytes::from_static(b"hash"), Bytes::from_static(b"field"), Bytes::from_static(b"value"));
