trait 实现

impl AsMut<Context> for Video

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

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Context> for Video

fn as_ref(&self) -> &Context

Converts this type into a shared reference of the (usually inferred) input type.

impl Deref for Video

type Target = Opened

解引用之后得到的类型。

fn deref(&self) -> &<Self as Deref>::Target

解引用该值。

impl DerefMut for Video

fn deref_mut(&mut self) -> &mut <Self as Deref>::Target

Mutably dereferences the value.
