Struct ClockSelectorDescriptor 

pub struct ClockSelectorDescriptor {
    pub clock_id: u8,
    pub source_ids: Vec<u8, MAX_CLOCK_DESCRIPTORS>,
    pub controls_bitmap: u8,
    pub clock_name: StringIndex,
}

Clock selector descriptor for selecting between multiple clock sources. (USB Audio Devices 2.0 §4.7.2.2)

Fields

clock_id: u8

Unique identifier for this clock selector.

source_ids: Vec<u8, MAX_CLOCK_DESCRIPTORS>

List of source clock IDs that can be selected.

controls_bitmap: u8

Bitmap of supported controls.

clock_name: StringIndex

Index of string descriptor describing this clock selector.

Implementations

impl ClockSelectorDescriptor

pub const SUPPORTED_SOURCE_IDS: u8 = 8u8

Maximum number of source ids that we support (at most 248).

Trait Implementations

impl Clone for ClockSelectorDescriptor

fn clone(&self) -> ClockSelectorDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClockSelectorDescriptor

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

Formats the value using the given formatter.

impl Format for ClockSelectorDescriptor

where Vec<u8, MAX_CLOCK_DESCRIPTORS>: Format, StringIndex: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for ClockSelectorDescriptor

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

const BUF_SIZE: usize = 15usize

Size of the byte buffer.

const DESC_TYPE: u8 = 36u8

Descriptor type.

const DESC_SUBTYPE: Option<u8>

Descriptor subtype.

type Error = AudioInterfaceError

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

impl VariableSizeDescriptor for ClockSelectorDescriptor

fn match_bytes_len(bytes: &[u8]) -> bool

Matches length with the number of source ids.

const MIN_LEN: u8 = 7u8

Minimum length of the descriptor.

const MAX_LEN: u8 = 255u8

Maximum 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 WritableDescriptor for ClockSelectorDescriptor

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.
