Trait Implementations

impl Clone for Video

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Deref for Video

type Target = Frame

The resulting type after dereferencing.

fn deref(&self) -> &Frame

Dereferences the value.

impl DerefMut for Video

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

Mutably dereferences the value.

impl From<Frame> for Video

fn from(frame: Frame) -> Self

Converts to this type from the input type.

impl PartialEq for Video

fn eq(&self, other: &Video) -> 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.
