Required Methods§

fn GetPropCount(&self) -> Result<u16>

fn GetPropByIndex( &self, windex: u16, pwszname: PWSTR, pcchnamelen: *mut u16, ptype: *mut WMT_ATTR_DATATYPE, pvalue: *mut u8, pcblength: *mut u16, ) -> Result<()>

fn GetPropByName( &self, pszname: &PCWSTR, ptype: *mut WMT_ATTR_DATATYPE, pvalue: *mut u8, pcblength: *mut u16, ) -> Result<()>

fn SetProp( &self, pszname: &PCWSTR, type: WMT_ATTR_DATATYPE, pvalue: *const u8, cblength: u16, ) -> Result<()>

fn RemoveProp(&self, pcwszname: &PCWSTR) -> Result<()>

fn RemoveAllProps(&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.
