Struct FunctionBuilder

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

Function builder.

A function is a logical grouping of interfaces that perform a given USB function. If Config::composite_with_iads is set, each function will have an IAD descriptor. If not, functions will not be visible as descriptors.

Implementations

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

pub fn interface(&mut self) -> InterfaceBuilder<'_, 'd, D>

Add an interface to the function.

Interface numbers are guaranteed to be allocated consecutively, starting from 0.

pub fn msos_feature<T: FunctionLevelDescriptor>(&mut self, desc: T)

Add an MS OS 2.0 Function Level Feature Descriptor.

Trait Implementations

impl<'a, 'd, D: Driver<'d>> Drop for FunctionBuilder<'a, 'd, D>

fn drop(&mut self)

Executes the destructor for this type.
