Struct graphene::Size

pub struct Size { /* private fields */ }

A size.

GLib type: Inline allocated boxed type with stack copy semantics.

Implementations

impl Size

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

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const graphene_size_t) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut graphene_size_t, ) -> &'a mut Self

Borrows the underlying C value mutably.

impl Size

pub fn interpolate(&self, b: &Size, factor: f64) -> Size

Linearly interpolates the two given Size using the given interpolation factor.

b

a Size

factor

the linear interpolation factor

Returns

res

return location for the interpolated size

pub fn scale(&self, factor: f32) -> Size

Scales the components of a Size using the given factor.

factor

the scaling factor

Returns

res

return location for the scaled size

pub fn zero() -> Size

A constant pointer to a zero Size, useful for equality checks and interpolations.

Returns

a constant size

impl Size

pub fn new(width: f32, height: f32) -> Self

Initializes a Size using the given width and height.

width

the width

height

the height

Returns

the initialized Size

pub fn width(&self) -> f32

pub fn set_width(&mut self, width: f32)

pub fn height(&self) -> f32

pub fn set_height(&mut self, height: f32)

Trait Implementations

impl Clone for Size

fn clone(&self) -> Self

Copies the inline boxed type by value with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl HasParamSpec for Size

type ParamSpec = ParamSpecBoxed

type SetValue = Size

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

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

fn param_spec_builder() -> Self::BuilderFn

impl PartialEq for Size

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl StaticType for Size

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for Size

impl Eq for Size
