Struct AttrFloat

pub struct AttrFloat { /* private fields */ }

GLib type: Boxed type with copy-on-clone semantics.

Implementations

impl AttrFloat

pub fn as_ptr(&self) -> *mut PangoAttrFloat

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut PangoAttrFloat) -> &Self

Trait Implementations

impl AsRef<Attribute> for AttrFloat

fn as_ref(&self) -> &Attribute

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

impl Clone for AttrFloat

fn clone(&self) -> Self

Copies the boxed type with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for AttrFloat

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

Formats the value using the given formatter.

impl Deref for AttrFloat

type Target = Attribute

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for AttrFloat

fn deref_mut(&mut self) -> &mut Attribute

Mutably dereferences the value.

impl From<AttrFloat> for Attribute

fn from(attr: AttrFloat) -> Attribute

Converts to this type from the input type.

impl From<AttrFloat> for Value

fn from(o: AttrFloat) -> Self

Converts to this type from the input type.

impl HasParamSpec for AttrFloat

type ParamSpec = ParamSpecBoxed

type SetValue = AttrFloat

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, AttrFloat>

fn param_spec_builder() -> Self::BuilderFn

impl IsAttribute for AttrFloat

const ATTR_TYPES: &'static [AttrType] = _

fn upcast(self) -> Attribute

fn upcast_ref(&self) -> &Attribute

impl PartialEq for AttrFloat

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StaticType for AttrFloat

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for AttrFloat

impl Send for AttrFloat

impl Sync for AttrFloat
