Expand description

An async abstraction over connections.

Required Methods§

Source

fn req_packed_command<'a>( &'a mut self, cmd: &'a Cmd, ) -> Pin<Box<dyn Future<Output = Result<Value, RedisError>> + Send + 'a>>

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

Source

fn req_packed_commands<'a>( &'a mut self, cmd: &'a Pipeline, offset: usize, count: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<Value>, RedisError>> + Send + 'a>>

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

Source

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.
