Struct 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 const fn interface_number(&self) -> InterfaceNumber

Get the interface number.

pub const 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 bos_capability(&mut self, capability_type: u8, capability: &[u8])

Add a custom Binary Object Store (BOS) descriptor to this alternate setting.

pub fn endpoint_descriptor( &mut self, endpoint: &EndpointInfo, synchronization_type: SynchronizationType, usage_type: UsageType, extra_fields: &[u8], )

Write a custom endpoint descriptor for a certain endpoint.

This can be necessary, if the endpoint descriptors can only be written after the endpoint was created. As an example, an endpoint descriptor may contain the address of an endpoint that was allocated earlier.

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

Allocate an IN endpoint, without writing its descriptor.

Used for granular control over the order of endpoint and descriptor creation.

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

Allocate an OUT endpoint, without writing its descriptor.

Use for granular control over the order of endpoint and descriptor creation.

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, synchronization_type: SynchronizationType, usage_type: UsageType, extra_fields: &[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, synchronization_type: SynchronizationType, usage_type: UsageType, extra_fields: &[u8], ) -> D::EndpointOut

Allocate a ISOCHRONOUS OUT endpoint and write its descriptor.
