Trait Implementations

impl Clone for Sample

fn clone(&self) -> Sample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sample

impl Debug for Sample

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

Formats the value using the given formatter.

impl Eq for Sample

impl From<&'static str> for Sample

fn from(value: &'static str) -> Self

Converts to this type from the input type.

impl From<AVSampleFormat> for Sample

fn from(value: AVSampleFormat) -> Self

Converts to this type from the input type.

impl From<Sample> for AVSampleFormat

fn from(value: Sample) -> AVSampleFormat

Converts to this type from the input type.

impl PartialEq for Sample

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