Implementations

impl Command

pub fn from_str(name: &'static str) -> Command

Constructs a command from a 'static str reference.

If the string does not refer to a built-in command, a value of Command::Custom(Borrowed(name)) will be returned.

pub fn from_string<T>(name: T) -> Command

where T: AsRef<str> + Into<String>,

Constructs a command from a non-'static string-like type.

If the string does not refer to a built-in command, a value of Command::Custom(Owned(name.into())) will be returned.

impl Command

pub fn category(&self) -> Category

Returns the category of the command

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a copy 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 Default for Command

fn default() -> Self

Returns the “default value” for a type.

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.

impl Eq for Command

impl StructuralPartialEq for Command
