Trait Implementations

impl Clone for Caps

fn clone(&self) -> Caps

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Transfer<GstCaps> for Caps

unsafe fn transfer(self) -> *mut GstCaps

Consumes the current object and transfers ownership of the raw pointer Used to transfer ownership to ffi functions, should be used when an ffi function expects full transfer of an object to avoid the original object to be unreferenced in the process

impl PartialEq for Caps

fn eq(&self, other: &Caps) -> 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 !=.

impl Eq for Caps

impl AsRef<MiniObject> for Caps

fn as_ref(&self) -> &MiniObject

Performs the conversion.

impl AsMut<MiniObject> for Caps

fn as_mut(&mut self) -> &mut MiniObject

Performs the conversion.

impl Deref for Caps

type Target = MiniObject

The resulting type after dereferencing

fn deref(&self) -> &MiniObject

The method called to dereference a value

impl DerefMut for Caps

fn deref_mut(&mut self) -> &mut MiniObject

The method called to mutably dereference a value
