Implementations

Returns true if self is a success code.

Returns true if self is a failure code.

Asserts that self is a success code.

This will invoke the panic! macro if self is a failure code and display the HRESULT value for diagnostics.

Converts the HRESULT to Result<()>.

Returns the Option as a Result if the option is a Some value, returning a suitable error if not.

Calls op if self is a success code, otherwise returns HRESULT converted to Result<T>.

Safety

If the Result is Ok converts the T::Abi into T.

The error message describing the error.
