Struct redis::Connection

pub struct Connection {
    // some fields omitted
}

Represents a stateful redis TCP connection.

Methods

impl Connection

A connection is an object that represents a single redis connection. It provides basic support for sending encoded commands into a redis connection and to read a response from it. It's bound to a single database and can only be created from the client.

You generally do not much with this object other than passing it to Cmd objects.

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

Sends an already encoded (packed) command into the TCP socket and does not read a response. This is useful for commands like MONITOR which yield multiple items. This needs to be used with care because it changes the state of the connection.

fn recv_response(&self) -> RedisResult<Value>

Fetches a single response from the connection. This is useful if used in combination with send_packed_command.

fn set_write_timeout(&self, dur: Option<Duration>) -> RedisResult<()>

Sets the write timeout for the connection.

If the provided value is None, then send_packed_command call will block indefinitely. It is an error to pass the zero Duration to this method.

fn set_read_timeout(&self, dur: Option<Duration>) -> RedisResult<()>

Sets the read timeout for the connection.

If the provided value is None, then recv_response call will block indefinitely. It is an error to pass the zero Duration to this method.

Trait Implementations

impl ConnectionLike for Connection

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.
