Struct Waveform 

pub struct Waveform { /* private fields */ }

Realtime audio waveform widget.

Implementations

impl Waveform

pub fn new() -> Self

Create an empty waveform.

pub fn samples(self, samples: Vec<f32>) -> Self

Replace the sample buffer (builder form).

pub fn set_samples(&mut self, samples: &[f32])

Replace the sample buffer in place; call this once per frame.

pub fn color(self, color: Color) -> Self

Set the line colour.

pub fn line_width(self, width: f32) -> Self

Set the line width (negative values become 0; NaN and infinities become 0 and huge values are clamped to +-1e15, so the stroke is always finite).

pub fn max_points(self, max_points: usize) -> Self

Set the upper bound on drawn points.

pub fn width(self, width: f32) -> Self

Set the preferred width.

Negative values become 0 and values above 1e15 are clamped to it; NaN and infinities count as “not set”, so measure falls back to the default width instead of reporting a non-finite size.

pub fn height(self, height: f32) -> Self

Set the preferred height (same rules as Waveform::width).

pub fn size(self, width: f32, height: f32) -> Self

Set both preferred width and height.

pub fn accessible_name(self, name: impl Into<String>) -> Self

Set the accessible name.

pub fn test_id(self, id: impl Into<String>) -> Self

Set the test ID.

pub fn get_samples(&self) -> &[f32]

The raw sample buffer.

pub const fn get_color(&self) -> Color

The line colour.

pub fn get_line_width(&self) -> f32

The line width.

pub const fn get_max_points(&self) -> usize

The upper bound on drawn points.

pub fn peak(&self) -> f32

Largest magnitude among the samples after clamping; 0.0 when empty.

pub fn rms(&self) -> f32

Root mean square of the samples after clamping; 0.0 when empty.
