Struct InterfaceAssociationDescriptor 

pub struct InterfaceAssociationDescriptor {
    pub first_interface: u8,
    pub num_interfaces: u8,
    pub class: u8,
    pub subclass: u8,
    pub protocol: u8,
    pub interface_name: StringIndex,
}

USB interface association descriptor for grouping related interfaces.

This descriptor is used to associate multiple interfaces that belong to the same function, such as an audio function with control and streaming interfaces.

Fields

first_interface: u8

First interface number in the association.

num_interfaces: u8

Number of interfaces in the association.

class: u8

Function class code.

subclass: u8

Function subclass code.

protocol: u8

Function protocol code.

interface_name: StringIndex

Index of string descriptor describing the function.

Implementations

impl InterfaceAssociationDescriptor

pub fn is_audio_association(&self) -> bool

Returns true if this interface association is for an audio function.

Trait Implementations

impl Debug for InterfaceAssociationDescriptor

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

Formats the value using the given formatter.

impl Format for InterfaceAssociationDescriptor

where StringIndex: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for InterfaceAssociationDescriptor

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

const SIZE: usize = 8usize

const DESC_TYPE: u8 = 11u8

type Error = ()

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