# Enum actix_redis::RespValue

[−]

    pub enum RespValue {
        Nil,
        Array(Vec<RespValue, Global>),
        BulkString(Vec<u8, Global>),
        Error(String),

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, Global>)`

Zero, one or more other `RespValue`s.

### `BulkString(Vec<u8, Global>)`

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
