IStream methods from ole feature.

Provided Methods

fn Commit(&self, flags: STGC) -> HrResult<()>

IStream::Commit method.

fn CopyTo( &self, dest: &impl ole_IStream, num_bytes: u64 ) -> HrResult<(u64, u64)>

IStream::CopyTo method.

Returns the number of bytes read and written.

fn LockRegion( &self, offset: u64, length: u64, lock_type: LOCKTYPE ) -> HrResult<()>

IStream::LockRegion method.

Note: Must be paired with an IStream::UnlockRegion call.

fn Revert(&self) -> HrResult<()>

IStream::Revert method.

fn Seek(&self, displacement: i64, origin: STREAM_SEEK) -> HrResult<u64>

IStream::Seek method.

Returns the new absolute offset.

fn SetSize(&self, new_size: u64) -> HrResult<()>

IStream::SetSize method.

fn UnlockRegion( &self, offset: u64, length: u64, lock_type: LOCKTYPE ) -> HrResult<()>

IStream::UnlockRegion method.
