Required Methods

unsafe fn Count(&self, Count: *mut i32) -> HRESULT

Returns the number of tracks in the collection.

unsafe fn Item(&self, Index: i32, iTrack: *mut Option<IITTrack>) -> HRESULT

Returns an IITTrack object corresponding to the given fixed index, where the index is independent of the play order (1-based).

unsafe fn ItemByPlayOrder( &self, Index: i32, iTrack: *mut Option<IITTrack>, ) -> HRESULT

Returns an IITTrack object corresponding to the given index, where the index is defined by the play order of the playlist containing the track collection (1-based).

unsafe fn ItemByName( &self, Name: BSTR, iTrack: *mut Option<IITTrack>, ) -> HRESULT

Returns an IITTrack object with the specified name.

unsafe fn _NewEnum(&self, iEnumerator: *mut Option<IEnumVARIANT>) -> HRESULT

Returns an IEnumVARIANT object which can enumerate the collection.

Note: I have not figured out how to use it (calling .Skip(1) on the returned IEnumVARIANT causes a STATUS_ACCESS_VIOLATION).
Feel free to open an issue or a pull request to fix this.

unsafe fn ItemByPersistentID( &self, highID: i32, lowID: i32, iTrack: *mut Option<IITTrack>, ) -> HRESULT

Returns an IITTrack object with the specified persistent ID.

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.
