fn from(value: &OwnerRef<Source, Target>) -> Self

Converts to this type from the input type.

impl<Source: ?Sized> From<Owner<Source>> for OwnerRef<Source, Source>

fn from(value: Owner<Source>) -> Self

Converts to this type from the input type.

impl<Source: ?Sized, Target: ?Sized> From<OwnerRef<Source, Target>> for Holder<Source>

fn from(value: OwnerRef<Source, Target>) -> Self

Converts to this type from the input type.

impl<Source: ?Sized, Target: ?Sized> From<OwnerRef<Source, Target>> for Owner<Source>

impl<Source: ?Sized, Target: ?Sized> Hash for OwnerRef<Source, Target>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl<Source: ?Sized, Target: ?Sized> PartialEq for OwnerRef<Source, Target>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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