Implementations

impl Waveform

pub fn sample(&self, time: f32) -> f32

Evaluate the waveform at an absolute time in seconds.

Trait Implementations

impl Clone for Waveform

fn clone(&self) -> Waveform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Waveform

impl Debug for Waveform

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

Formats the value using the given formatter.

impl PartialEq for Waveform

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