Enum redis_async::resp::RespValue

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

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 RespValues.

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)

Methods

impl RespValue

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

Trait Implementations

impl FromResp for RespValue

fn from_resp_int(resp: RespValue) -> Result<RespValue, Error>

fn from_resp(resp: RespValue) -> Result<Self, Error>

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.

impl<'a> From<String> for RespValue

fn from(from: String) -> RespValue

Performs the conversion.

impl<'a> From<&'a String> for RespValue

fn from(from: &'a String) -> RespValue

Performs the conversion.

impl<'a> From<&'a str> for RespValue

fn from(from: &'a str) -> RespValue

Performs the conversion.

impl<'a> From<&'a [u8]> for RespValue

fn from(from: &'a [u8]) -> RespValue

Performs the conversion.

impl<'a> From<Vec<u8>> for RespValue

fn from(from: Vec<u8>) -> RespValue

Performs the conversion.

impl<'a> From<usize> for RespValue

fn from(from: usize) -> RespValue

Performs the conversion.

impl Clone for RespValue

fn clone(&self) -> RespValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for RespValue

impl PartialEq<RespValue> for RespValue

fn eq(&self, other: &RespValue) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for RespValue

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
