# Enum actix_redis::RespValue

    pub enum RespValue {
        Nil,
        Array(Vec<RespValue>),

Expand description

A single RESP value, this owns the data that is read/to-be written to Redis.

It is cloneable to allow multiple copies to be delivered in certain circumstances, e.g. multiple subscribers to the same topic.

## Variants§

§

### Nil

§

### Array(Vec<RespValue>)

Zero, one or more other `RespValue`s.

§

### BulkString(Vec<u8>)

A bulk string. In Redis terminology a string is a byte-array, so this is stored as a vector of `u8`s to allow clients to interpret the bytes as appropriate.

§

### Error(String)

An error from the Redis server

§

### Integer(i64)

Redis documentation defines an integer as being a signed 64-bit integer: https://redis.io/topics/protocol#resp-integers

§

### SimpleString(String)

## Implementations§

§

### impl RespValue

#### pub fn append<T>(self, other: impl IntoIterator<Item = T>) -> RespValue
where T: Into<RespValue>,

Convenience function for building dynamic Redis commands with variable numbers of arguments, e.g. RPUSH

This will panic if called for anything other than arrays

#### pub fn push<T>(&mut self, item: T)
where T: Into<RespValue>,

Push item to Resp array

This will panic if called for anything other than arrays

#### fn ne(&self, other: &Rhs) -> bool

This method tests for `!=`. The default implementation is almost always sufficient, and should not be overridden without very good reason.
