Struct Dim

pub struct Dim {
    pub pixels: f32,
    pub percent: f32,
}

Describes a length consisting of one or more measurements added together.

This struct is inspired by CSS’s unit system, which is a very flexible way to talk about the size of widgets in a layout.

The equivalent CSS for a given Dim is:

calc(dim.pixels + 100 * dim.percent)

where dim.pixels is the px unit in CSS and dim.percent is the % unit in CSS.

Fields

pixels: f32

The portion of the value in logical pixels. Works like the px unit in CSS.

percent: f32

A value scaled based on the parent object’s measurement on the axis. 1.0 corresponds to 100% of the parent width, while 0.0 corresponds to 0%.

Implementations

impl Dim

pub const ZERO: Self

A Dim corresponding to a length of zero.

pub const fn pixels(pixels: f32) -> Self

Returns a Dim with the given length in pixels.

pub const fn percent(percent: f32) -> Self

Returns a Dim with the given length as a percentage of the parent container.

pub fn resolve(&self, parent_length: f32) -> f32

Resolves the Dim to a single value in pixels using information about the surrounding context.

Trait Implementations

impl Clone for Dim

fn clone(&self) -> Dim

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dim

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

Formats the value using the given formatter.

impl Default for Dim

fn default() -> Dim

Returns the “default value” for a type.

impl PartialEq for Dim

fn eq(&self, other: &Dim) -> 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 Copy for Dim

impl StructuralPartialEq for Dim
