impl Gradient
pub fn add_color_stop_rgb(&self, offset: f64, red: f64, green: f64, blue: f64)

Methods from Deref<Target = Pattern>§
Sourcepub fn set_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>,
value: Rc<T>,
)
pub fn set_user_data<T: 'static>( &self, key: &'static UserDataKey<T>, value: Rc<T>, )
Attach user data to self
for the given key
.
Sourcepub fn get_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>,
) -> Option<Rc<T>>
pub fn get_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 get_user_data_ptr<T: 'static>(
&self,
key: &'static UserDataKey<T>,
) -> Option<NonNull<T>>
pub fn get_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>)
pub fn remove_user_data<T: 'static>(&self, key: &'static UserDataKey<T>)
Unattach from self
the user data associated with key
, if any.
If there is no other Rc
strong reference, the data is destroyed.
