Enum Matching 

pub enum Matching {
    Exact,
    Transposed,
    Transformed,
    Multiset,
    TransposedMultiset,
    TransposedInvertedMultiset,
}

How a SegmentMatcher tells a run of pitch classes the same as one searched for.

Variants

Exact

The same pitch classes in the same order: music21’s SegmentMatcher.

Transposed

The same intervals in the same order: music21’s TransposedSegmentMatcher.

Transformed

A transposition, inversion, retrograde or retrograde inversion: music21’s TransformedSegmentMatcher.

Multiset

The same pitch classes in any order: music21’s MultisetSegmentMatcher.

TransposedMultiset

The same pitch classes in any order, transposed: music21’s TransposedMultisetMatcher.

TransposedInvertedMultiset

The same pitch classes in any order, transposed or inverted: music21’s TransposedInvertedMultisetMatcher.

Implementations

impl Matching

pub fn equal_segments( self, search: &[IntegerType], subset: &[IntegerType], ) -> bool

Whether a run’s pitch classes are the segment searched for, as this matcher tells the two the same: music21’s equalSubset, given the classes each reading was made from rather than the readings.

The order is music21’s: the segment searched for first, which is the one a transposing matcher moves.

Trait Implementations

impl Clone for Matching

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Matching

impl Debug for Matching

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Matching

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Matching

impl Hash for Matching

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Matching

fn eq(&self, other: &Self) -> bool

Equality operator ==.
