Implementations

impl<T> Size<T>

pub fn get_abs(self, axis: AbsoluteAxis) -> T

Get either the width or height depending on the AbsoluteAxis passed in

impl<T> Size<T>

pub fn map<R, F>(self, f: F) -> Size<R>

where F: Fn(T) -> R,

Applies the function f to both the width and height

This is used to transform a Size<T> into a Size<R>.

pub fn map_width<F>(self, f: F) -> Size<T>

where F: Fn(T) -> T,

Applies the function f to the width

pub fn map_height<F>(self, f: F) -> Size<T>

where F: Fn(T) -> T,

Applies the function f to the height

pub fn zip_map<Other, Ret, Func>(self, other: Size<Other>, f: Func) -> Size<Ret>

where Func: Fn(T, Other) -> Ret,

Applies the function f to both the width and height of this value and another passed value

impl Size<f32>

pub const ZERO: Size<f32> = _

A Size with zero width and height

pub fn f32_max(self, rhs: Size<f32>) -> Size<f32>

Applies f32_max to each component separately

pub fn f32_min(self, rhs: Size<f32>) -> Size<f32>

Applies f32_min to each component separately

pub fn has_non_zero_area(self) -> bool

Return true if both width and height are greater than 0 else false

impl Size<Option<f32>>

pub const NONE: Size<Option<f32>> = _

A Size with None width and height

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

A Size<Option<f32>> with Some(width) and Some(height) as parameters

pub fn maybe_apply_aspect_ratio( self, aspect_ratio: Option<f32>, ) -> Size<Option<f32>>

Applies aspect_ratio (if one is supplied) to the Size:

• If width is Some but height is None, then height is computed from width and aspect_ratio
• If height is Some but width is None, then width is computed from height and aspect_ratio

If aspect_ratio is None then this function simply returns self.

impl<T> Size<Option<T>>

pub fn unwrap_or(self, alt: Size<T>) -> Size<T>

Performs Option::unwrap_or on each component separately

pub fn or(self, alt: Size<Option<T>>) -> Size<Option<T>>

Performs Option::or on each component separately

pub fn both_axis_defined(&self) -> bool

Return true if both components are Some, else false.

impl Size<Dimension>

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

Generates a Size<Dimension> using Dimension::Length values

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

Generates a Size<Dimension> using Dimension::Percent values

impl Size<AvailableSpace>

pub fn into_options(self) -> Size<Option<f32>>

Convert Size<AvailableSpace> into Size<Option<f32>>

pub fn maybe_set(self, value: Size<Option<f32>>) -> Size<AvailableSpace>

If passed value is Some then return AvailableSpace::Definite containing that value, else return self

impl<T: TaffyZero> Size<T>

pub const fn zero() -> Self

Returns a Size where both the width and height values are the zero value of the contained type (e.g. 0.0, Some(0.0), or Dimension::Length(0.0))

impl<T: TaffyAuto> Size<T>

pub const fn auto() -> Self

Returns a Size where both the width and height values are the auto value of the contained type (e.g. Dimension::Auto or LengthPercentageAuto::Auto)

impl<T: TaffyMinContent> Size<T>

pub const fn min_content() -> Self

Returns a Size where both the width and height values are the min_content value of the contained type (e.g. Dimension::Auto or LengthPercentageAuto::Auto)

impl<T: TaffyMaxContent> Size<T>

pub const fn max_content() -> Self

Returns a Size where both the width and height values are the max_content value of the contained type (e.g. Dimension::Auto or LengthPercentageAuto::Auto)

impl<T: TaffyFitContent> Size<T>

pub fn fit_content(argument: LengthPercentage) -> Self

Returns a Size where with width and height set to the same fit-content(…) value with the given argument.

impl<T: FromLength> Size<T>

pub fn length<Input: Into<f32> + Copy>(value: Input) -> Self

Returns a Size where both the width and height values the same given absolute length

impl<T: FromPercent> Size<T>

pub fn percent<Input: Into<f32> + Copy>(percent_value: Input) -> Self

Returns a Size where both the width and height values are the constant percent value of the contained type (e.g. 2.1, Some(2.1), or Dimension::Length(2.1))
