Trait Implementations

impl Clone for Audio

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Audio

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Deref for Audio

type Target = Frame

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for Audio

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

Mutably dereferences the value.

impl From<Frame> for Audio

fn from(frame: Frame) -> Self

Converts to this type from the input type.

impl PartialEq<Audio> for Audio

fn eq(&self, other: &Audio) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
