Enum Value 

pub enum Value {
    Simple(String),
    Error(String),
    Integer(i64),
    Bulk(Vec<u8>),
    Nil,
    Array(Vec<Value>),
}

One decoded RESP value.

Variants

Simple(String)

+OK — a status reply.

Error(String)

-ERR ... — an error reply. Carried as a value rather than a Rust error so the decoder stays total and the caller decides what is fatal.

Integer(i64)

:42

Bulk(Vec<u8>)

$5\r\nhello — arbitrary bytes, not necessarily UTF-8.

Nil

$-1 or *-1 — the absence of a value, which is how Redis says “no such key”.

Array(Vec<Value>)

*2\r\n...

Implementations

impl Value

pub fn as_str(&self) -> Option<&str>

Interpret a reply as text, whatever shape it arrived in.

pub fn as_bytes(&self) -> Option<&[u8]>

pub fn as_i64(&self) -> Option<i64>

An integer reply, or a bulk string that happens to hold digits — Redis answers TTL with the first and GET on a counter with the second.

pub fn is_nil(&self) -> bool

pub fn into_result(self) -> Result<Value>

Convert an error reply into a Rust error, leaving anything else alone.

pub fn encode(&self) -> Vec<u8>

Serialize back to the wire. Used by the round-trip tests and by the in-process fake server they run against.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Eq for Value

impl PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.
