Enum IdemMut 

pub enum IdemMut<'a, T>
where
    T: ToOwning,
{
    Change(&'a mut T),
    Keep(&'a mut T::Owning),
}

Provides a mutable reference to either a T or a T::Owning.

Variants

Change(&'a mut T)

Provides a mutable reference to a T.

Keep(&'a mut T::Owning)

Provides a mutable reference to a T::Owning.

Trait Implementations

impl<'a, T> Debug for IdemMut<'a, T>

where T: ToOwning + Debug, T::Owning: Debug,

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

Formats the value using the given formatter.

impl<'a, T> PartialEq for IdemMut<'a, T>

where T: ToOwning + PartialEq, T::Owning: PartialEq,

fn eq(&self, other: &IdemMut<'a, 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.

impl<'a, T> Eq for IdemMut<'a, T>

where T: ToOwning + Eq, T::Owning: Eq,

impl<'a, T> StructuralPartialEq for IdemMut<'a, T>

where T: ToOwning,
