Enum CommandClass 

pub enum CommandClass {
    Argz,
    Arg0,
    Arg1,
    Arg2,
    Arg3,
    ArgN,
    ArgX,
    ArgKvX,
    ArgUpto1,
    ArgEval,
}

Argument-shape classification for a Redis request command.

Variants

Argz

Command takes no key (PING, QUIT, SCRIPT FLUSH, …).

Arg0

Command takes exactly one key and zero arguments.

Arg1

Command takes one key and exactly one argument.

Arg2

Command takes one key and exactly two arguments.

Arg3

Command takes one key and exactly three arguments.

ArgN

Command takes one key and zero-or-more arguments (variadic).

ArgX

Command takes one or more keys (MGET, DEL, EXISTS).

ArgKvX

Command takes one or more key/value pairs (MSET).

ArgUpto1

Command takes one key and zero or one argument (INFO).

ArgEval

Command is EVAL or EVALSHA (special two-arg + key list + args layout).

Implementations

impl CommandClass

pub fn is_argz(self) -> bool

True when the command takes no key.

pub fn is_argx(self) -> bool

True when the command is variadic over keys.

pub fn is_argkvx(self) -> bool

True when the command is variadic over key/value pairs.

pub fn is_argeval(self) -> bool

True when the command is EVAL or EVALSHA.

Trait Implementations

impl Clone for CommandClass

fn clone(&self) -> CommandClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandClass

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

Formats the value using the given formatter.

impl PartialEq for CommandClass

fn eq(&self, other: &CommandClass) -> 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.
