Struct ParameterAutomation 

pub struct ParameterAutomation {
    pub points: Vec<AutomationPoint>,
    pub looping: bool,
}

Parameter automation data

Fields

points: Vec<AutomationPoint>

Automation points

looping: bool

Whether to loop the automation

Implementations

impl ParameterAutomation

pub fn new() -> Self

Create new automation

pub fn add_point(self, time: f64, value: f64) -> Self

Add an automation point

pub fn with_curve(self, curve: AutomationCurve) -> Self

Set the curve type

pub fn with_loop(self, looping: bool) -> Self

Enable looping

pub fn value_at_time(&self, time: f64) -> Option<f64>

Get value at specific time

pub fn points_for_block( &self, block_start_secs: f64, frames: usize, sample_rate: f64, points_per_block: usize, ) -> Vec<(i32, f64)>

Sample this automation across one audio block, returning (sample_offset, value) points suitable for sample-accurate scheduling (e.g. Plugin::set_parameter_at).

block_start_secs is the block’s start on the automation timeline; frames is the block length; points_per_block is the sub-block resolution (1 = one value at the block start; higher = finer ramps, capped at frames). Returns empty if the automation has no points.

Trait Implementations

impl Clone for ParameterAutomation

fn clone(&self) -> ParameterAutomation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterAutomation

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

Formats the value using the given formatter.

impl Default for ParameterAutomation

fn default() -> Self

Returns the “default value” for a type.
