Struct InForce 

pub struct InForce {
    pub clef: Option<Clef>,
    pub key: Option<KeySignature>,
    pub meter: Option<TimeSignature>,
}

The clef, key and time signature in force before a measure, which music21 finds by searching the measure’s context and Stream::split_at_quarter_length is given: a crate stream knows nothing outside itself. Stream::in_force_before reads them off a part.

Fields

clef: Option<Clef>

The clef in force before the measure.

key: Option<KeySignature>

The key signature in force before the measure.

meter: Option<TimeSignature>
