Struct Duration 

pub struct Duration { /* private fields */ }

Rhythmic duration measured in quarter lengths.

A quarter note has a quarter length of 1.0; an eighth note is 0.5; a whole note is 4.0.

Implementations

impl Duration

pub fn new(quarter_length: FloatType) -> Result<Self>

Creates a duration from a quarter-length value.

pub fn quarter() -> Self

Returns a quarter-note duration.

pub fn half() -> Self

Returns a half-note duration.

pub fn whole() -> Self

Returns a whole-note duration.

pub fn eighth() -> Self

Returns an eighth-note duration.

pub fn quarter_length(&self) -> FloatType

Returns the duration in quarter lengths.

pub fn set_quarter_length(&mut self, quarter_length: FloatType) -> Result<()>

Updates the duration in quarter lengths.

Trait Implementations

impl Clone for Duration

fn clone(&self) -> Duration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Duration

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

Formats the value using the given formatter.

impl Default for Duration

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Duration

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Duration> for Rest

fn from(value: Duration) -> Self

Converts to this type from the input type.

impl PartialEq for Duration

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Duration

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<f64> for Duration

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: FloatType) -> Result<Self>

Performs the conversion.

impl TryFrom<i32> for Duration

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: IntegerType) -> Result<Self>

Performs the conversion.
