Implementations

impl<'a> ProcessContext<'a>

pub fn new( transport: &'a TransportInfo, sample_rate: f64, block_size: usize, output_events: &'a mut EventList, ) -> Self

pub fn with_params(self, f: &'a dyn Fn(u32) -> f64) -> Self

Set the parameter lookup callback.

pub fn with_meters(self, f: &'a dyn Fn(u32, f32)) -> Self

Set the meter reporting callback.

pub fn param(&self, id: u32) -> f64

Read a parameter’s plain value by ID.

pub fn set_meter(&self, id: impl Into<u32>, value: f32)

Report a meter value (0.0 to 1.0).

pub fn sync_params<P: Params>(&self, events: &EventList, params: &mut P)

Sync a Params struct with parameter changes from the given events.
