Struct TempoModel 

pub struct TempoModel {
    pub text: Option<String>,
    pub beat: Option<TempoBeat>,
    pub beat_role: TempoBeatRole,
    pub source_span: Span,
}

A parsed ABC Q: tempo field, structured for MusicXML <metronome> export.

The raw field text is preserved in ScoreMetadata::tempo; this model adds the interpreted beat unit, beats-per-minute and any leading quoted text so the writer can emit a real metronome direction rather than plain words.

Fields

text: Option<String>

Optional quoted text accompanying the tempo (e.g. "Allegro").

beat: Option<TempoBeat>

Beat unit and bpm, when the field carries a numeric tempo.

beat_role: TempoBeatRole

Whether the numeric tempo was a visible metronome or playback-only MusicXML <sound tempo>. ABC Q: creates visible metronomes; imported playback-only tempo uses a croma carrier so the round trip does not print a metronome that was absent from the source.

source_span: Span
