Struct Beam 

pub struct Beam { /* private fields */ }

One beam at one level: music21’s beam.Beam.

Implementations

impl Beam

pub fn new( beam_type: impl Into<Option<BeamType>>, direction: Option<BeamDirection>, ) -> Self

A beam of the given type, with a direction only a partial one needs.

pub fn beam_type(&self) -> Option<BeamType>

Whether the beam starts, carries on, ends, or is a stub — and nothing at all where that has not been decided.

pub fn set_beam_type(&mut self, beam_type: Option<BeamType>)

Says what the beam does at this note.

pub fn direction(&self) -> Option<BeamDirection>

Which way a stub points, and nothing for a beam that is not one.

pub fn set_direction(&mut self, direction: Option<BeamDirection>)

Points a stub the other way.

pub fn number(&self) -> Option<u32>

Which level this beam is: the first is the one an eighth note has.

pub fn set_number(&mut self, number: Option<u32>)

Puts the beam at a level.
