Struct redis::Client

pub struct Client { /* fields omitted */ }

The client type.

Methods

impl Client

The client acts as connector to the redis server. By itself it does not do much other than providing a convenient way to fetch a connection from it. In the future the plan is to provide a connection pool in the client.

When opening a client a URL in the following format should be used:

redis://host:port/db

Example usage::

let client = redis::Client::open("redis://127.0.0.1/").unwrap();
let con = client.get_connection().unwrap();

pub fn open<T: IntoConnectionInfo>(params: T) -> RedisResult<Client>

Connects to a redis server and returns a client. This does not actually open a connection yet but it does perform some basic checks on the URL that might make the operation fail.

pub fn get_connection(&self) -> RedisResult<Connection>

Instructs the client to actually connect to redis and returns a connection object. The connection object can be used to send commands to the server. This can fail with a variety of errors (like unreachable host) so it's important that you handle those errors.

pub fn get_async_connection(
    &self
) -> impl Future<Item = Connection, Error = RedisError>

pub fn get_shared_async_connection(
    &self
) -> impl Future<Item = SharedConnection, Error = RedisError>

Trait Implementations

impl ConnectionLike for Client

fn req_packed_command(&self, cmd: &[u8]) -> RedisResult<Value>

Sends an already encoded (packed) command into the TCP socket and reads the single response from it.

fn req_packed_commands(
    &self,
    cmd: &[u8],
    offset: usize,
    count: usize
) -> RedisResult<Vec<Value>>

Sends multiple already encoded (packed) command into the TCP socket and reads count responses from it. This is used to implement pipelining.

fn get_db(&self) -> i64

Returns the database this connection is bound to. Note that this information might be unreliable because it's initially cached and also might be incorrect if the connection like object is not actually connected.
