Struct Staff 

pub struct Staff {
    pub voices: Vec<StaffVoice>,
}

Identity-bearing canonical score timeline.

A staff is the lossless interlingua for note-bearing catalog forms. It retains voice boundaries, exact rational timing, trailing silence, and stable note/event identities without requiring those concerns in the lightweight Note value.

Fields

voices: Vec<StaffVoice>

Independent or simultaneous voices.

Implementations

impl Staff

pub fn new(voices: Vec<StaffVoice>) -> Result<Self, ConversionError>

Builds and validates a staff, sorting voices and notes canonically.

pub fn duration(&self) -> Time

Returns the exact parallel span of all voices.

pub fn notes(&self) -> impl Iterator<Item = &StaffNote>

Iterates over all notes in canonical voice/time order.

pub fn object_ids(&self) -> Vec<ObjectId>

Returns every voice, note, and event identity in sorted order.
