Enum StemDirection 

pub enum StemDirection {
    Double,
    Down,
    NoStem,
    Unspecified,
    Up,
}

Which way the stem points: music21’s stemDirectionNames.

Variants

Double

Stems both up and down, for a divided part.

Down

Stem down.

NoStem

Written with no stem at all, as a harmonic sounding pitch is.

Unspecified

Not said, the default.

Up

Stem up.

Implementations

impl StemDirection

pub const ALL: [StemDirection; 5]

Every stem direction a note can hold.

One shorter than music21’s StemDirection::NAMES: "none" is an input spelling of "noStem" that music21’s setter rewrites, so no note ever reads back as "none".

pub const NAMES: [&'static str; 6]

music21’s stemDirectionNames: the names the setter accepts, which includes the "none" spelling of "noStem".

pub fn as_str(self) -> &'static str

music21’s name for the direction.

pub fn from_name(name: &str) -> Result<Self>

Reads music21’s name for the direction.

"none" reads as StemDirection::NoStem, which is what music21’s setter stores for it.
