Enum Value 

pub enum Value {
    Integer(i64),
    Float(FloatType),
}

One value of a Feature: a whole number, as a count or an index is, or a float, as a share or a measurement is. music21 keeps the two apart, a vector starting as whole noughts, and writes them apart – 4 and 4.0 – in a data set.

Variants

Integer(i64)

A whole number.

Float(FloatType)

A float.

Implementations

impl Value

pub fn as_float(self) -> FloatType

The value as a float, whichever it is.

pub fn is_integer(self) -> bool

Whether it is a whole number rather than a float.

Trait Implementations

impl Clone for Value

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 Value

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Value

Available on crate feature serde only.

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

Written as Python writes it: 4 for the whole number, 4.0 for the float, the fewest digits that read back as the float.

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

Formats the value using the given formatter.
