Implementations

impl Ruler

pub fn new<T>(total_width: f64, desc: RangeDescription<T>) -> Ruler where
    T: Iterator<Item = TimeSig> + Clone, 

Constructor for a Ruler.

pub fn markers_in_ticks<I>(
    &self,
    bars: I,
    ppqn: Ppqn
) -> MarkersInTicks<WithStarts<I::IntoIter>> where
    I: IntoIterator<Item = TimeSig>,
    I::IntoIter: Clone, 

Produce an iterator that yields an iterator for each bar along with its start position in ticks.

pub fn markers_in_divisions<I>(
    &self,
    bars: I,
    ppqn: Ppqn
) -> MarkersInDivisions<WithStarts<I::IntoIter>> where
    I: IntoIterator<Item = TimeSig>,
    I::IntoIter: Clone, 

Produce an iterator that yields an iterator for each bar that yields each marker’s simplest division representation suitable for the Ruler.

pub fn marker_count<I>(&self, bars: I, ppqn: Ppqn) -> usize where
    I: IntoIterator<Item = TimeSig>,
    I::IntoIter: Clone, 

Produces the number of visible markers on the Ruler for the given bars.

pub fn ticks_per_width(&self, ppqn: Ppqn) -> Scalar

The fractional number of ticks that may fit within one unit of space.
