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

NilArray(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: &mut Vec<T>) -> Self where
    T: Into<RespValue>, 

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

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 Eq for RespValue

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 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<'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 Debug for RespValue

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

Formats the value using the given formatter.
