sourcepub fn set_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>,
value: Rc<T>
) -> Result<(), Error>
pub fn set_user_data<T: 'static>( &self, key: &'static UserDataKey<T>, value: Rc<T> ) -> Result<(), Error>
Attach user data to self
for the given key
.
sourcepub fn user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<Rc<T>>
pub fn user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<Rc<T>>
Return the user data previously attached to self
with the given key
, if any.
sourcepub fn user_data_ptr<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<NonNull<T>>
pub fn user_data_ptr<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<NonNull<T>>
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.
sourcepub fn remove_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Result<(), Error>
pub fn remove_user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Result<(), Error>
Unattached from self
the user data associated with key
, if any.
If there is no other Rc
strong reference, the data is destroyed.
sourcepub fn finish_output_stream(&self) -> Result<Box<dyn Any>, StreamWithError>
pub fn finish_output_stream(&self) -> Result<Box<dyn Any>, StreamWithError>
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
.
