Required Methods§
Sourcefn instance(&self) -> BorrowedObject<'_, Self::Type>
👎Deprecated: Use obj() instead
fn instance(&self) -> BorrowedObject<'_, Self::Type>
Returns the corresponding object instance.
Sourcefn from_instance(obj: &Self::Type) -> &Self
👎Deprecated: Use from_obj() instead
fn from_instance(obj: &Self::Type) -> &Self
Returns the implementation from an instance.
Sourcefn obj(&self) -> BorrowedObject<'_, Self::Type>
fn obj(&self) -> BorrowedObject<'_, Self::Type>
Returns the corresponding object instance.
Shorter alias for instance()
.
Sourcefn from_obj(obj: &Self::Type) -> &Self
fn from_obj(obj: &Self::Type) -> &Self
Returns the implementation from an instance.
Shorter alias for from_instance()
.
Sourcefn ref_counted(&self) -> ObjectImplRef<Self>
fn ref_counted(&self) -> ObjectImplRef<Self>
Returns a new reference-counted wrapper around self
.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
