Enum Library 

pub enum Library {
    Piano,
    Sample,
    Program,
    SetList,
}

One of the instrument’s stored libraries — what a ControlKind::Reference id is an id into.

A file carries the id alone, so nothing but this says which catalogue resolves it. Listed here are the libraries something in a decoded body actually refers to; the instruments hold others (the live slots, the settings singleton) that no reference points at, and they are not here.

Variants

Piano

Piano instruments (.npno).

Sample

Sample instruments (.nsmp).

Program

The instrument’s own programs.

SetList

Set lists, which name programs in turn.

Implementations

impl Library

pub const fn code(self) -> u8

The library’s numeric code.

It exists because a const generic parameter cannot be an enum: a type that carries its library — LibraryRefOf — carries this instead and turns it back with from_code.

The numbers are the object-class codes the instruments use on the wire, and nord-usb’s ObjectClass takes its library codes from here, so a caller holding both has one table.

pub const fn from_code(code: u8) -> Option<Library>

The library a code names, or None — most bytes name none.

pub const fn expect_code(code: u8) -> Library

The library a code names, for the type-level parameter this vocabulary exists to carry.

⚠️ Panics on a code naming none. That is a build failure only where the value is forced at compile time, which the aliases in components are — a LibraryRefOf<7> nobody places compiles clean and fails when a field declared with it asks for its control kind. Use from_code anywhere a code arrives at runtime.

pub fn label(&self) -> &'static str

The catalogue’s name, singular, as a caller would put it in front of “id”.
