Struct ScaleInfo 

pub struct ScaleInfo {
    pub root: i8,
    pub mask: u16,
    pub name: [u8; 32],
    pub name_len: u8,
}

Scale/key information from DAW.

Provides tonal context that plugins can use for scale-aware processing.

Fields

root: i8

Root note pitch class (0=C, 1=C#, …, 11=B), -1 = invalid/unknown.

mask: u16

Bitmask of scale degrees (12 bits for chromatic scale). Bit 0 = root, bit 1 = minor 2nd, bit 2 = major 2nd, etc.

name: [u8; 32]

Scale name as UTF-8 (e.g., “Major”, “Dorian”, “Pentatonic”).

name_len: u8

Actual length of name.

Implementations

impl ScaleInfo

pub fn name_str(&self) -> &str

Get the scale name as a string slice.

pub fn is_valid(&self) -> bool

Check if the scale info is valid.

pub fn contains(&self, pitch_class: u8) -> bool

Check if a pitch class (0-11) is in the scale.

Trait Implementations

impl Clone for ScaleInfo

fn clone(&self) -> ScaleInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleInfo

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

Formats the value using the given formatter.

impl PartialEq for ScaleInfo

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.
