Enum redif::Value

pub enum Value {
    Nil,
    NullArray,
    Int(i64),
    Data(Vec<u8>),
    Bulk(Vec<Value>),
    Status(String),
    Error(String),
}

Represents a RESP value, see Redis Protocol specification.

Variants

Nil

A nil response, $-1\r\n

NullArray

Null array response, *-1\r\n

Int(i64)

An integer response. Note that there are a few situations in which redis actually returns a string for an integer which is why this library generally treats integers and strings the same for all numeric responses. With the first byte of the response is ":".

Data(Vec<u8>)

An arbitary binary data. With the first byte of the response is "$".

Bulk(Vec<Value>)

A bulk response of more data. This is generally used by redis to express nested structures. With the first byte of the response is "*".

Status(String)

A status response with the first byte of the response is "+".

Error(String)

An error response with the first byte of the response is "-".

Trait Implementations

impl PartialEq for Value

fn eq(&self, __arg_0: &Value) -> bool

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

fn ne(&self, __arg_0: &Value) -> bool

This method tests for !=.

impl Eq for Value

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.
