Struct Spacing 

pub struct Spacing {
    pub s0: f32,
    pub s1: f32,
    pub s2: f32,
    pub s3: f32,
    pub s4: f32,
    pub s6: f32,
    pub s8: f32,
    pub s12: f32,
    pub s16: f32,
    pub rhythm: RhythmScale,
}

The 4 px spacing scale every gap, inset and gutter is drawn from.

Copy so a const context can read a step (Spacing::BASE.s3) for the handful of chrome constants that must be compile-time values; everything with a Theme in hand reads theme.tokens.spacing.*, which is already scaled by crate::Theme::with_ui_scale and by a custom theme’s spacing_px.

Fields

s0: f32

s1: f32

s2: f32

s3: f32

s4: f32

s6: f32

s8: f32

s12: f32

s16: f32

rhythm: RhythmScale

The scale named by relationship: how far apart two things are follows from how they relate, so one relationship never carries two different gaps.

Implementations

impl Spacing

pub const BASE: Spacing

Unscaled reference scale: 0 / 4 / 8 / 12 / 16 / 24 / 32 / 48 / 64. Spacing::default returns this; a const that has to agree with a token (a shell breakpoint composed from a gutter, say) reads it directly instead of restating the number.

pub fn step(&self, step: SpacingStep) -> f32

The step’s value on this (possibly scaled) scale.

pub fn scaled(&self, factor: f32) -> Spacing

Every step multiplied by factor (ui_scale, or a custom theme’s spacing_px / BASE.s3). Proportions between steps are preserved, so a widget that pairs s2 with s4 keeps its 1:2 rhythm at any scale.

Trait Implementations

impl Clone for Spacing

fn clone(&self) -> Spacing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Spacing

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

Formats the value using the given formatter.

impl Default for Spacing

fn default() -> Spacing

Returns the “default value” for a type.

impl PartialEq for Spacing

fn eq(&self, other: &Spacing) -> 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 Spacing
