Attach user data to self
for the given key
.
Return the user data previously attached to self
with the given key
, if any.
Return the user data previously attached to self
with the given key
, if any,
without incrementing the reference count.
The pointer is valid when it is returned from this method,
until the cairo object that self
represents is destroyed
or remove_user_data
or set_user_data
is called with the same key.
Unattached from self
the user data associated with key
, if any.
If there is no other Rc
strong reference, the data is destroyed.
This is supported on crate features pdf
or svg
or ps
or dox
only.

only.Finish the surface, then remove and return the output stream if any.
This calls Surface::finish
, to make sure pending writes are done.
This is relevant for surfaces created for example with [PdfSurface::for_stream
].
Use Box::downcast
to recover the concrete stream type.
Panics
This method panics if:
- This method was already called for this surface, or
- This surface was not created with an output stream in the first place, or
- A previous write to this surface panicked, or
- A previous write happened while another write was ongoing, or
- A write is ongoing now.
The latter two cases can only occur with a pathological output stream type
that accesses the same surface again from Write::write_all
.
