Struct Drawbars 

pub struct Drawbars(/* private fields */);

Nine drawbar positions, nibble-packed high-nibble first — the on-disk form every organ model shares.

Positions are physical, 0..=8, stored identity. Decoding is total: a nibble outside that range is preserved rather than refused. Drawbars::new refuses one on the way in.

Per-model display transforms — Farfisa’s on/off threshold, Vox’s ignored 8th bar, the b3-bass remap — are not applied here.

Implementations

impl Drawbars

pub const BARS: usize = 9

The number of bars, and so the nibbles this occupies.

pub const MAX: u8 = 8

The highest position a drawbar can be pulled to.

pub fn new(bars: [u8; 9]) -> Result<Self, ParseError>

Nine positions, each 0..=8.

pub fn positions(&self) -> [u8; 9]

The nine positions as stored.

Trait Implementations

impl Clone for Drawbars

fn clone(&self) -> Drawbars

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Drawbars

impl Debug for Drawbars

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

The positions alone, so a panel’s Debug reads as the array it is.

impl Default for Drawbars

fn default() -> Drawbars

Returns the “default value” for a type.

impl Display for Drawbars

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

888000000 — the form the corpus filenames use.

impl Eq for Drawbars

impl Packed for Drawbars

const CONTROL: ControlKind

The whole register in one field, so the first bar is the leftmost one and the nibbles run down from the top of the slot.

const MAX_BITS: u32

Bits the widest value of this type occupies. Used to check statically that it fits its slot.

const DECODE_BITS: u32 = Self::MAX_BITS

Widest slot this type can decode without losing bits on re-encoding.

type Error = !

Why a bit pattern is not a valid value. Infallible when every pattern is.

fn from_bits(bits: u64) -> Result<Self, Self::Error>

Decode from the field’s bits, already shifted down to bit 0 and masked.

fn to_bits(&self) -> u64

Encode to the field’s bits, in the same shifted-down form.

impl PartialEq for Drawbars

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

Equality operator ==.

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

Inequality operator !=.
