    B: ToOwned + ?Sized,{
    Const(&'a B),
    Mut(&'a mut B::Owned),
}

Returned by StaticCow::mut_if_owned.

Variants

Trait Implementations

impl<'a, B> Debug for MutIfOwned<'a, B>where
    B: ToOwned + ?Sized + Debug,
    B::Owned: Debug,

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

Formats the value using the given formatter.

impl<'a, B> PartialEq<MutIfOwned<'a, B>> for MutIfOwned<'a, B>where
    B: ToOwned + ?Sized + PartialEq,
    B::Owned: PartialEq,

fn eq(&self, other: &MutIfOwned<'a, B>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
