Struct TempoSpan 

pub struct TempoSpan {
    pub start: FloatType,
    pub end: FloatType,
    pub mark: MetronomeMark,
    pub position: Option<usize>,
}

One stretch of a stream and the tempo sounding through it: a boundary of music21’s metronomeMarkBoundaries.

Fields

start: FloatType

Where the stretch begins.

end: FloatType

Where it ends, which is where the next tempo stands, or the end of the stream for the last.

mark: MetronomeMark

The tempo sounding through it.

position: Option<usize>

The position among Stream::leaves of the mark the stream holds, where the tempo is one of its own: nothing for the quarter at 120 standing in for a stream that states none, and nothing for what a tempo word or a metric modulation means.
