Struct AudioEndpointDescriptor 

pub struct AudioEndpointDescriptor {
    pub attributes_bitmap: u8,
    pub controls_bitmap: u8,
    pub lock_delay_units: u8,
    pub lock_delay: u16,
}

Audio-specific endpoint descriptor containing audio endpoint attributes. (USB Audio Devices 2.0 §4.10.1.2)

Fields

attributes_bitmap: u8

Bitmap of endpoint attributes.

controls_bitmap: u8

Bitmap of supported controls.

lock_delay_units: u8

Units for lock delay (1=milliseconds, 2=samples).

lock_delay: u16

Lock delay value in the specified units.

Trait Implementations

impl Clone for AudioEndpointDescriptor

fn clone(&self) -> AudioEndpointDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioEndpointDescriptor

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

Formats the value using the given formatter.

impl ExtendableDescriptor for AudioEndpointDescriptor

const MIN_LEN: u8 = 8u8

Minimum length of the descriptor.

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

Matches bytes with this descriptor.

fn prepare_bytes(bytes: &mut [u8], len: u8) -> Result<(), DescriptorError>

where Self: WritableDescriptor,

Prepares bytes to receive descriptor data.

impl Format for AudioEndpointDescriptor

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

Writes the defmt representation of self to fmt.

impl PartialEq for AudioEndpointDescriptor

fn eq(&self, other: &AudioEndpointDescriptor) -> 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 AudioEndpointDescriptor

const BUF_SIZE: usize = 8usize

Size of the byte buffer.

const DESC_TYPE: u8 = 37u8

Descriptor type.

const DESC_SUBTYPE: Option<u8>

Descriptor subtype.

type Error = DescriptorError

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

impl WritableDescriptor for AudioEndpointDescriptor

fn write_to_bytes(&self, bytes: &mut [u8]) -> Result<usize, Self::Error>

Writes this descriptor to the start of the byte buffer bytes.

fn write_to_bytes_partial(&self, bytes: &mut [u8]) -> Result<usize, Self::Error>

Writes this descriptor to the start of the byte buffer bytes.
