Implementations

impl Command

pub fn from_frame(frame: Frame) -> Result<Command, ProtocolError>

Parses a Frame into a Command.

Expects an array frame where the first element is the command name (as a bulk or simple string) and the rest are arguments.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

fn eq(&self, other: &Command) -> 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 Eq for Command

impl StructuralPartialEq for Command
