Enum Part 

#[non_exhaustive]
pub enum Part {
    WindowGround,
    FloatingPanel,
    BarBody,
    ControlFace,
    ButtonContainer,
    FocusRing,
    ScrollTrack,
    ScrollThumb,
}

A part a ui component declares. A theme reaches parts, never an app’s view tree.

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.

WindowGround

The ground of a window, which every app paints on.

FloatingPanel

The body of floating chrome: a menu, popover, sheet, notification.

BarBody

The body of the top bar.

ControlFace

The face of a raised control: a field, dropdown, segmented strip, card. tokens.fill is its face colour.

ButtonContainer

The container of a button. tokens.fill, ink and edge are the face colours its role and state resolved to.

FocusRing

The ring that marks keyboard focus, around the part it belongs to.

ScrollTrack

The track of a scroll bar.

ScrollThumb

The thumb of a scroll bar.

Implementations

impl Part

pub const ALL: [Part; 8]

Every part, in wire order.

pub fn index(self) -> u8

Its index in Self::ALL, as the wire carries it.

pub fn from_index(index: u8) -> Option<Part>

The part at index in Self::ALL.

Trait Implementations

impl Clone for Part

fn clone(&self) -> Part

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Part

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

Formats the value using the given formatter.

impl Hash for Part

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

where __H: Hasher,

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 Part

fn cmp(&self, other: &Part) -> 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.

impl PartialEq for Part

fn eq(&self, other: &Part) -> 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 PartialOrd for Part

fn partial_cmp(&self, other: &Part) -> 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.
