Struct PendingOffs 

pub struct PendingOffs { /* private fields */ }

Every note this track is holding, oldest first.

Oldest-first is maintained by removing with a shift rather than a swap, which is what makes “overflow forces off the oldest” a one-line operation on a table of thirty-two. The shift is at most 32 moves of 24 bytes.

Implementations

impl PendingOffs

pub const fn new() -> Self

pub const fn len(&self) -> usize

pub const fn is_empty(&self) -> bool

pub fn clear(&mut self)

Forget everything without sounding an off. For a panic, where the instruments are being reset underneath us anyway.

pub fn hold( &mut self, lane: usize, note: u8, due: Option<i64>, now: i64, out: &mut impl EventSink, )

Note that note is sounding on lane.

When the table is full the oldest note is turned off at now and its slot reused. Never drops the new note: a note with no off in the table is a note nothing will ever stop.

pub fn end_lane(&mut self, lane: usize, at: i64, out: &mut impl EventSink)

Turn off everything held on lane, at at.

Called immediately before a lane’s next onset, which is what ends a tied note and what keeps a gate longer than a step from running over its own next hit.

pub fn emit_due_before(&mut self, tick: i64, out: &mut impl EventSink)

Turn off everything whose off is due before tick, each at its own due tick.

pub fn flush(&mut self, at: i64, out: &mut impl EventSink)

Turn off everything, at at. Stop, pause, a position jump, a loop wrap, a pattern switch: every discontinuity ends every note.
