Enum FeaturesVersion 

pub enum FeaturesVersion {
    Version2 = 2,
    Version1 = 1,
}

The versions of the features used for analysis. Used for backwards-compatibility reasons in case people want to keep using older features version.

Songs analyzed with different FeaturesVersion are not compatible with one another, as they might have a different set of features, etc.

Variants

Version2 = 2

The latest iteration, increasing chroma features accuracy and making feature normalization more coherent.

Version1 = 1

The first iteration of the features. The 4 last chroma features (song mode detection) might underperform / be underused while computing distances.

Implementations

impl FeaturesVersion

pub const LATEST: FeaturesVersion = FeaturesVersion::Version2

Always points to the latest features’ version. In case of doubt, use this one.

pub const fn feature_count(self) -> usize

Number of features for this version (usable in const contexts).

Trait Implementations

impl Clone for FeaturesVersion

fn clone(&self) -> FeaturesVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeaturesVersion

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

Formats the value using the given formatter.

impl Default for FeaturesVersion

fn default() -> FeaturesVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FeaturesVersion

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FeaturesVersion> for u16

fn from(v: FeaturesVersion) -> Self

Converts to this type from the input type.

impl FromSql for FeaturesVersion

fn column_result(value: ValueRef<'_>) -> FromSqlResult<Self>

Converts SQLite value into Rust value.

impl Ord for FeaturesVersion

fn cmp(&self, other: &FeaturesVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FeaturesVersion

fn eq(&self, other: &FeaturesVersion) -> 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 PartialOrd for FeaturesVersion

fn partial_cmp(&self, other: &FeaturesVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u16> for FeaturesVersion

type Error = BlissError

The type returned in the event of a conversion error.

fn try_from(value: u16) -> Result<Self, Self::Error>

Performs the conversion.
