Trait Implementations

impl<M: Clone> Clone for Cmd<M>

fn clone(&self) -> Cmd<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug> Debug for Cmd<M>

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

Formats the value using the given formatter.

impl<M> Default for Cmd<M>

fn default() -> Cmd<M>

Returns the “default value” for a type.

impl<M: PartialEq> PartialEq for Cmd<M>

fn eq(&self, other: &Cmd<M>) -> 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.
