Extension trait providing higher-level control request methods on a USB control pipe.

Provided Methods

async fn request_descriptor<T: USBDescriptor, const SIZE: usize>( &mut self, index: u8, class: bool, ) -> Result<T, HostError>

where D: IsIn,

Request and parse a fixed-size descriptor.

async fn request_descriptor_bytes( &mut self, desc_type: u8, index: u8, buf: &mut [u8], ) -> Result<usize, HostError>

where D: IsIn,

Request the raw bytes of a descriptor by type and index.

async fn interface_request_descriptor_bytes<T: USBDescriptor>( &mut self, interface_num: u8, buf: &mut [u8], ) -> Result<usize, HostError>

where D: IsIn,

Request the raw bytes of a class-specific interface descriptor.

async fn active_configuration_value( &mut self, ) -> Result<Option<NonZeroU8>, HostError>

where D: IsIn,

GET_CONFIGURATION — returns the active configuration value, or None if unconfigured.

async fn set_configuration(&mut self, config_no: u8) -> Result<(), HostError>

where D: IsOut,

SET_CONFIGURATION.

async fn device_set_address(&mut self, new_addr: u8) -> Result<(), HostError>

where D: IsOut,

SET_ADDRESS — assign the device a new address.

Warning

Breaks host channel state; use only during enumeration.

async fn class_request_out( &mut self, request: u8, value: u16, index: u16, buf: &[u8], ) -> Result<(), HostError>

where D: IsOut,

Class + Interface OUT request (no data stage).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
