Required Methods§

fn IsSupported(&self, api: *const GUID) -> Result<()>

fn IsAvailable(&self, api: *const GUID) -> Result<()>

fn GetParameterRange( &self, api: *const GUID, valuemin: *mut VARIANT, valuemax: *mut VARIANT, steppingdelta: *mut VARIANT, ) -> Result<()>

fn GetParameterValues( &self, api: *const GUID, values: *mut *mut VARIANT, valuescount: *mut u32, ) -> Result<()>

fn GetDefaultValue(&self, api: *const GUID) -> Result<VARIANT>

fn GetValue(&self, api: *const GUID) -> Result<VARIANT>

fn SetValue(&self, api: *const GUID, value: *const VARIANT) -> Result<()>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
