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 RespValues.

§

BulkString(Vec<u8, Global>)

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§

§

impl RespValue

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