Methods from Deref<Target = Pattern>

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.

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.

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.

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.

Trait Implementations

impl AsRef<Pattern> for Mesh

fn as_ref(&self) -> &Pattern

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Mesh

fn clone(&self) -> Mesh

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mesh

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Mesh

fn default() -> Self

Returns the “default value” for a type.

impl Deref for Mesh

type Target = Pattern

The resulting type after dereferencing.

fn deref(&self) -> &Pattern

Dereferences the value.

impl Display for Mesh

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl TryFrom<Pattern> for Mesh

type Error = Pattern

The type returned in the event of a conversion error.

fn try_from(pattern: Pattern) -> Result<Self, Pattern>

Performs the conversion.
