Struct embassy_usb::InterfaceAltBuilder

pub struct InterfaceAltBuilder<'a, 'd, D: Driver<'d>> { /* private fields */ }

Interface alternate setting builder.

Implementations

impl<'a, 'd, D: Driver<'d>> InterfaceAltBuilder<'a, 'd, D>

pub fn interface_number(&self) -> InterfaceNumber

Get the interface number.

pub fn alt_setting_number(&self) -> u8

Get the alternate setting number.

pub fn descriptor(&mut self, descriptor_type: u8, descriptor: &[u8])

Add a custom descriptor to this alternate setting.

Descriptors are written in the order builder functions are called. Note that some classes care about the order.

pub fn endpoint_bulk_in(&mut self, max_packet_size: u16) -> D::EndpointIn

Allocate a BULK IN endpoint and write its descriptor.

Descriptors are written in the order builder functions are called. Note that some classes care about the order.

pub fn endpoint_bulk_out(&mut self, max_packet_size: u16) -> D::EndpointOut

Allocate a BULK OUT endpoint and write its descriptor.

Descriptors are written in the order builder functions are called. Note that some classes care about the order.

pub fn endpoint_interrupt_in( &mut self, max_packet_size: u16, interval_ms: u8 ) -> D::EndpointIn

Allocate a INTERRUPT IN endpoint and write its descriptor.

Descriptors are written in the order builder functions are called. Note that some classes care about the order.

pub fn endpoint_interrupt_out( &mut self, max_packet_size: u16, interval_ms: u8 ) -> D::EndpointOut

Allocate a INTERRUPT OUT endpoint and write its descriptor.

pub fn endpoint_isochronous_in( &mut self, max_packet_size: u16, interval_ms: u8 ) -> D::EndpointIn

Allocate a ISOCHRONOUS IN endpoint and write its descriptor.

Descriptors are written in the order builder functions are called. Note that some classes care about the order.

pub fn endpoint_isochronous_out( &mut self, max_packet_size: u16, interval_ms: u8 ) -> D::EndpointOut

Allocate a ISOCHRONOUS OUT endpoint and write its descriptor.
