Required Methods§

fn GetCount(&self) -> Result<u32>

fn Get( &self, key: *const PROPERTYKEY, ppropvar: *mut PROPVARIANT, pdwpropertyconstraint: *mut u32, ) -> Result<()>

fn Item( &self, dwindex: u32, pkey: *mut PROPERTYKEY, ppropvar: *mut PROPVARIANT, pdwpropertyconstraint: *mut u32, ) -> Result<()>

fn Next( &self, pkey: *mut PROPERTYKEY, ppropvar: *mut PROPVARIANT, pdwpropertyconstraint: *mut u32, ) -> Result<()>

fn Skip(&self) -> Result<()>

fn Reset(&self) -> 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.
