Required Methods

fn open( &mut self, address: String, ) -> impl Future<Output = Result<Resource<Connection>, Error>> + Send

Open a connection to the Redis instance at address.

fn publish( &mut self, self_: Resource<Connection>, channel: String, payload: Payload, ) -> impl Future<Output = Result<(), Error>> + Send

Publish a Redis message to the specified channel.

fn get( &mut self, self_: Resource<Connection>, key: String, ) -> impl Future<Output = Result<Option<Payload>, Error>> + Send

Get the value of a key.

fn set( &mut self, self_: Resource<Connection>, key: String, value: Payload, ) -> impl Future<Output = Result<(), Error>> + Send

Set key to value.

If key already holds a value, it is overwritten.

fn incr( &mut self, self_: Resource<Connection>, key: String, ) -> impl Future<Output = Result<i64, Error>> + Send

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.

fn del( &mut self, self_: Resource<Connection>, keys: Vec<String>, ) -> impl Future<Output = Result<u32, Error>> + Send

Removes the specified keys.

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

fn sadd( &mut self, self_: Resource<Connection>, key: String, values: Vec<String>, ) -> impl Future<Output = Result<u32, Error>> + Send

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

fn smembers( &mut self, self_: Resource<Connection>, key: String, ) -> impl Future<Output = Result<Vec<String>, Error>> + Send

Retrieve the contents of the set named key.

fn srem( &mut self, self_: Resource<Connection>, key: String, values: Vec<String>, ) -> impl Future<Output = Result<u32, Error>> + Send

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

fn execute( &mut self, self_: Resource<Connection>, command: String, arguments: Vec<RedisParameter>, ) -> impl Future<Output = Result<Vec<RedisResult>, Error>> + Send

Execute an arbitrary Redis command and receive the result.

fn drop( &mut self, rep: Resource<Connection>, ) -> impl Future<Output = Result<()>> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
