Struct Arranger 

pub struct Arranger {
    pub placements: Vec<ArrangerPlacement>,
    pub lanes: Vec<LaneId>,
}

Arrangement of playable material laid out across lanes on a timeline.

Holds the ordered set of ArrangerPlacements plus the lane ids the arrangement declares, and renders them into play events.

Fields

placements: Vec<ArrangerPlacement>

Placements that make up the arrangement, in declaration order.

lanes: Vec<LaneId>

Lane ids the arrangement declares.

Implementations

impl Arranger

pub fn new( placements: Vec<ArrangerPlacement>, lanes: Vec<LaneId>, ) -> Result<Self>

Builds an arranger from placements and lane ids, validating each placement.

impl Arranger

pub fn to_expr(&self) -> Expr

Encodes the arrangement as a tagged music/arranger expression map.

pub fn from_expr(expr: &Expr) -> Result<Self>

Decodes an arrangement from a tagged music/arranger expression map.

impl Arranger

pub fn render_arrangement(&self, cx: &PlayContext) -> Result<ArrangerRender>

Renders the arrangement into clipped, stable-ordered play events.

Applies each placement’s stretch, transforms, pitch remap, and filter, clips events to the context range, and appends diagnostics and traces.

pub fn rendered_notes(&self) -> Vec<TimedNote>

Renders the arrangement and returns only its timed notes.

pub fn diagnostics(&self) -> Vec<ArrangerDiagnostic>

Renders the arrangement and returns only the diagnostics it raises.
