Implementations§

source§

impl Connection

source

pub fn open(address: &str) -> Result<Connection, Error>

Open a connection to the Redis instance at address.

source§

impl Connection

source

pub fn publish(&self, channel: &str, payload: &Payload) -> Result<(), Error>

Publish a Redis message to the specified channel.

source§

impl Connection

source

pub fn get(&self, key: &str) -> Result<Option<Payload>, Error>

Get the value of a key.

source§

impl Connection

source

pub fn set(&self, key: &str, value: &Payload) -> Result<(), Error>

Set key to value.

If key already holds a value, it is overwritten.

source§

impl Connection

source

pub fn incr(&self, key: &str) -> Result<i64, Error>

Increments the number stored at key by one.

If the key does not exist, it is set to 0 before performing the operation. An error::type-error is returned if the key contains a value of the wrong type or contains a string that can not be represented as integer.

source§

impl Connection

source

pub fn del(&self, keys: &[String]) -> Result<u32, Error>

Removes the specified keys.

A key is ignored if it does not exist. Returns the number of keys deleted.

source§

impl Connection

source

pub fn sadd(&self, key: &str, values: &[String]) -> Result<u32, Error>

Add the specified values to the set named key, returning the number of newly-added values.

source§

impl Connection

source

pub fn smembers(&self, key: &str) -> Result<Vec<String>, Error>

Retrieve the contents of the set named key.

source§

impl Connection

source

pub fn srem(&self, key: &str, values: &[String]) -> Result<u32, Error>

Remove the specified values from the set named key, returning the number of newly-removed values.

source§

impl Connection

source

pub fn execute( &self, command: &str, arguments: &[RedisParameter] ) -> Result<Vec<RedisResult>, Error>

Execute an arbitrary Redis command and receive the result.
