Enum Algorithm 

pub enum Algorithm {
    Wildcard,
    Rhythm,
    NoteName,
    Custom(fn(&StreamElement, &SearchTerm) -> Option<bool>),
}

How a StreamSearcher compares an element of the stream with the search term it is lined up with: each answers that they match, that they do not, or nothing, leaving it to the next.

Variants

Wildcard

A wildcard matches anything: music21’s wildcardAlgorithm.

Rhythm

A term of any length matches; one of another length does not: music21’s rhythmAlgorithm.

NoteName

A term or element with no name, or of another name, does not match: music21’s noteNameAlgorithm.

Custom(fn(&StreamElement, &SearchTerm) -> Option<bool>)

A comparison of one’s own.
