Enum redis_async::resp::RespValue

source · [−]

pub enum RespValue {
    Nil,
    Array(Vec<RespValue>),
    BulkString(Vec<u8>),
    Error(String),
    Integer(i64),
    SimpleString(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`

`BulkString(Vec<u8>)`

A bulk string. In Redis terminology a string is a byte-array, so this is stored as a vector of u8s 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

source

impl RespValue

source

pub fn append<T>(self, other: impl IntoIterator<Item = T>) -> Self 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

source

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

Push item to Resp array

This will panic if called for anything other than arrays

source

Return a Result containing either Self or Error. Errors can occur due to either: a) the particular RespValue being incompatible with the required type, or b) a remote Redis error occuring. Read more
