The client type.
Implementations§
Source§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.
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/dbExample usage::
let client = redis::Client::open("redis://127.0.0.1/").unwrap();
let con = client.get_connection().unwrap();Sourcepub fn open<T>(params: T) -> Result<Client, RedisError>where
T: IntoConnectionInfo,
pub fn open<T>(params: T) -> Result<Client, RedisError>where
T: IntoConnectionInfo,
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.
Sourcepub fn get_connection(&self) -> Result<Connection, RedisError>
pub fn get_connection(&self) -> Result<Connection, RedisError>
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.
Sourcepub fn get_connection_with_timeout(
&self,
timeout: Duration,
) -> Result<Connection, RedisError>
pub fn get_connection_with_timeout( &self, timeout: Duration, ) -> Result<Connection, RedisError>
Instructs the client to actually connect to redis with specified timeout 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.
Sourcepub fn get_connection_info(&self) -> &ConnectionInfo
pub fn get_connection_info(&self) -> &ConnectionInfo
Returns a reference of client connection info object.
