Struct MsOsDescriptorWriter

pub struct MsOsDescriptorWriter<'d> { /* private fields */ }

Writes a Microsoft OS 2.0 Descriptor set into a buffer.

Implementations

impl<'d> MsOsDescriptorWriter<'d>

pub fn is_empty(&self) -> bool

Returns true if the MS OS descriptor header has not yet been written

pub fn is_in_config_subset(&self) -> bool

Returns true if a configuration subset header has been started

pub fn is_in_function_subset(&self) -> bool

Returns true if a function subset header has been started and not yet ended

pub fn header(&mut self, windows_version: u32, vendor_code: u8)

Write the MS OS descriptor set header.

• windows_version is an NTDDI version constant that describes a windows version. See the windows_version module.
• vendor_code is the vendor request code used to read the MS OS descriptor set.

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

where T: DeviceLevelDescriptor,

Add a device level feature descriptor.

Note that some feature descriptors may only be used at the device level in non-composite devices. Those features must be written before the first call to Self::configuration.

pub fn configuration(&mut self, config: u8)

Add a configuration subset.

pub fn function(&mut self, first_interface: InterfaceNumber)

Add a function subset.

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

where T: FunctionLevelDescriptor,

Add a function level feature descriptor.

Note that some features may only be used at the function level. Those features must be written after a call to Self::function.

pub fn end_function(&mut self)

Ends the current function subset (if any)
