Struct ConfigurationDescriptor 

pub struct ConfigurationDescriptor {
    pub total_len: u16,
    pub num_interfaces: u8,
    pub configuration_value: u8,
    pub configuration_name: StringIndex,
    pub attributes: u8,
    pub max_power: u8,
}

Standard USB Configuration Descriptor.

When a configuration descriptor is requested, all related descriptors are returned. (USB 2.0 §9.6.3)

Fields

total_len: u16

Total length of data returned for this configuration.

The data includes this descriptor, interface descriptors, endpoint descriptors, and possibly other descriptors.

num_interfaces: u8

Number of interface descriptors.

configuration_value: u8

Configuration ID.

configuration_name: StringIndex

Configuration string.

attributes: u8

Configuration attribute bitmap.

max_power: u8

Maximum bus power that will be consumed in 2mA units.

Trait Implementations

impl Clone for ConfigurationDescriptor

fn clone(&self) -> ConfigurationDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigurationDescriptor

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

Formats the value using the given formatter.

impl ExtendableDescriptor for ConfigurationDescriptor

const MIN_LEN: u8 = 9u8

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 ConfigurationDescriptor

where StringIndex: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for ConfigurationDescriptor

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

const BUF_SIZE: usize = 9usize

Size of the byte buffer.

const DESC_TYPE: u8 = 2u8

Descriptor type.

type Error = DescriptorError

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

const DESC_SUBTYPE: Option<u8> = None

Descriptor subtype.

impl WritableDescriptor for ConfigurationDescriptor

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.
