#
BoundVoicePoolError::from_voice_pool

source

fn BoundVoicePoolError::from_voice_pool(e : VoicePoolError) -> BoundVoicePoolError

Lift a VoicePoolError to a BoundVoicePoolError. Used by BoundVoicePool's constructors after delegating to validate_voice_template (which now returns VoicePoolError after the boundary-type migration per ADR-0010).

#
VoiceControlError

source

pub(all) enum VoiceControlError {
  InvalidVoiceHandle(VoiceHandle)
  Graph(@dowdiness/moondsp/graph.GraphControlError
GraphControlError)

Debug)

impl Show for VoiceControlError

#
VoiceHandle

source

pub struct VoiceHandle {
  slot : Int
  generation : Int
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Generation-tagged voice handle. WHY generation counter: slot indices are reused after voice stealing. Without a generation tag, a stale handle from a stolen note could accidentally gate_off or pan the wrong voice occupying that slot. Every note_on increments the slot's generation; all operations compare the handle's generation against the slot's current generation.

VoicePool::active_voice_count

source

fn VoicePool::active_voice_count(self : VoicePool) -> Int

#
VoicePool::last_sanitized_count

source

fn VoicePool::last_sanitized_count(self : VoicePool) -> Int

Number of non-finite samples replaced with 0.0 during the most recent process() call, across both L and R output channels after mixdown.

#
VoicePool::new

source

fn VoicePool::new(compiled_template : @dowdiness/moondsp/graph.CompiledTemplate
CompiledTemplate, context : @dowdiness/moondsp/dsp.DspContext
DspContext, max_voices? : Int) -> Result[VoicePool, VoicePoolError]

WHY test_compile: validates the template structurally (reachable Output node, no invalid cycles, valid node indices) before accepting it. This is a correctness gate so that per-voice note_on compiles can assume the template is well-formed. The compiled result is discarded. WHY orphan-ADSR reject: VoicePool::note_on calls gate_on for every ADSR index in the template. If an ADSR is authored into the template but not wired to Output, optimize_graph eliminates it and gate_on would now return Err(OrphanNode). Rejecting at pool-construction time keeps the per-note gate_adsrs_at(...) loop infallible (it can .unwrap()) and surfaces the misconfiguration at the earliest observable point rather than at every note trigger. WHY adsr_authoring_indices snapshot: the pool's long-lived snapshot (used by note_on to gate ADSRs, and refreshed by set_template) stores only the indices needed for gating — not the full template — so the caller's CompiledTemplate can be freely discarded after VoicePool::new returns. optimize_graph does not mutate its input, so neither CompiledTemplate::analyze nor CompiledDsp::compile disturbs the caller's array.
