Trait Implementations

impl<T: Clone + Mutable> Clone for OptionMutation<T>

where T::Mutation: Clone,

fn clone(&self) -> OptionMutation<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Mutable> Debug for OptionMutation<T>

where T::Mutation: Debug,

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

Formats the value using the given formatter.

impl<T: PartialEq + Mutable> PartialEq for OptionMutation<T>

where T::Mutation: PartialEq,

fn eq(&self, other: &OptionMutation<T>) -> 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.
