Implementations

impl Command

pub fn get(s: &str) -> Command

Parse a command from a string.

Arguments

• s - The command string (case-insensitive).

Returns

The parsed command, or Command::Invalid for unknown commands.

pub fn parse(s: &str) -> CacheResult<Command>

Parse a command from a string, returning an error for invalid commands.

Arguments

• s - The command string (case-insensitive).

Returns

The parsed command, or an error for unknown commands.

pub fn as_str(&self) -> &'static str

Get the string representation of this command.

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 Display 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.
