Struct StringDescriptorZero 

pub struct StringDescriptorZero {
    pub lang_ids: Vec<u16, { _ }>,
}

String Descriptor Zero (USB 2.0 §9.6.7)

A descriptor with index 0 specifies which languages are supported by the device.

Fields

lang_ids: Vec<u16, { _ }>

LANGID codes

Trait Implementations

impl Clone for StringDescriptorZero

fn clone(&self) -> StringDescriptorZero

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringDescriptorZero

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

Formats the value using the given formatter.

impl Format for StringDescriptorZero

where Vec<u16, { _ }>: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for StringDescriptorZero

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

const BUF_SIZE: usize = 254usize

Size of the byte buffer.

const DESC_TYPE: u8 = 3u8

Descriptor type.

type Error = DescriptorError

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

const DESC_SUBTYPE: Option<u8> = None

Descriptor subtype.

impl VariableSizeDescriptor for StringDescriptorZero

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

Matches len with the size of a lang_id value.

const MIN_LEN: u8 = 2u8

Minimum length of the descriptor.

const MAX_LEN: u8 = 254u8

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 StringDescriptorZero

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.
