One way of writing a look by hand.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Colour

A colour written as a literal.

OpacityInk

opacity below 1 outside an animation, which is a quiet ink or a hover tone with no contrast floor under it.

MixedTint

color-mix of a status or accent intent, which the toned surfaces and hover tokens already resolve with a floor.

Length

A literal length where the geometry scale has the step: an edge, a spacing, a radius, a type size, a shadow offset or a measure.

Duration

A literal time in a transition or an animation, which the reduced-motion block cannot reach.

Face

A literal font-family.

TokenShadow

A custom property a generated sheet already defines, restated.

UndefinedVar

var() of a custom property that nothing defines, with no fallback.

InlineStyle

A style attribute that sets anything but custom properties.

StyleBlock

A <style> block in markup.

SvgPaint

An SVG fill or stroke attribute naming a paint of its own.

ScriptStyle

A script writing an element’s style, or markup that carries one.

Implementations

impl Rule

pub const ALL: &[Self]

Every rule, in report order.

pub const fn id(self) -> &'static str

The rule’s stable id, the key a ceiling or an exemption names it by.

pub fn from_id(id: &str) -> Option<Self>

The rule named by id.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rule

impl Debug for Rule

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

Formats the value using the given formatter.

impl Display for Rule

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

Formats the value using the given formatter.

impl Eq for Rule

impl Hash for Rule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Rule

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Rule

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Rule

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
