Struct AudioControlHeaderDescriptor 

pub struct AudioControlHeaderDescriptor {
    pub audio_device_class: (u8, u8),
    pub category: u8,
    pub controls_bitmap: u8,
}

Audio control header descriptor containing version and category information. (USB Audio Devices 2.0 §4.7.2)

Fields

audio_device_class: (u8, u8)

Audio device class version (major, minor).

category: u8

Category of the audio device.

controls_bitmap: u8

Bitmap of supported controls.

Trait Implementations

impl Clone for AudioControlHeaderDescriptor

fn clone(&self) -> AudioControlHeaderDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioControlHeaderDescriptor

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

Formats the value using the given formatter.

impl ExtendableDescriptor for AudioControlHeaderDescriptor

const MIN_LEN: u8 = 9u8

Minimum length of the descriptor.

fn match_bytes(bytes: &[u8]) -> Result<(), DescriptorError>

Matches bytes with this descriptor.

impl Format for AudioControlHeaderDescriptor

where (u8, u8): Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for AudioControlHeaderDescriptor

fn eq(&self, other: &AudioControlHeaderDescriptor) -> 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 USBDescriptor for AudioControlHeaderDescriptor

const BUF_SIZE: usize = 9usize

Size of the byte buffer.

const DESC_TYPE: u8 = 36u8

Descriptor type.

const DESC_SUBTYPE: Option<u8>

Descriptor subtype.

type Error = DescriptorError

fn try_from_bytes(bytes: &[u8]) -> Result<Self, Self::Error>
