Enum DataTypeToken 

#[repr(u8)]
pub enum DataTypeToken {
    BulkString = 36,
    Array = 42,
    SimpleString = 43,
    Error = 45,
    Integer = 58,
    Unknown = 59,
}

RESP signals data types by prepending these one-character tokens

Variants

BulkString = 36

A single binary-safe string up to 512 MB in length. Precedes a CRLF-terminated length describing the following string. Can also be used to signal non-existence of a value using a special format that is used to represent a null value i.e. “$-1\r\n”. Note the ‘empty’ string still CRLF-terminates unlike the null value i.e. “$0\r\n\r\n”.

Array = 42

Clients send commands to the Redis server using RESP arrays. Servers can also return collections of elements with arrays. Precedes a CRLF-terminated length describing the following array. Empty type: “*0\r\n”. Note that single elements to the array may be null, in which case the element will look like the null value as described in BulkString

SimpleString = 43

Used to transmit non-binary-safe strings. These strings cannot contain ‘\r’ or ‘\n’ and are terminated by “\r\n”.

Error = 45

Exactly like simple strings but errors should be treated by the client as exceptions.

Integer = 58

Like simple strings, but representing an integer.

Unknown = 59

Implementations

impl DataTypeToken

pub fn from_raw(val: u8) -> Self

Trait Implementations

impl Clone for DataTypeToken

fn clone(&self) -> DataTypeToken

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataTypeToken

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

Formats the value using the given formatter.

impl PartialEq for DataTypeToken

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u8> for DataTypeToken

type Error = TryFromPrimitiveError<DataTypeToken>

The type returned in the event of a conversion error.

fn try_from(number: u8) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for DataTypeToken

const NAME: &'static str = "DataTypeToken"

type Primitive = u8

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for DataTypeToken

impl Eq for DataTypeToken

impl StructuralPartialEq for DataTypeToken
