ButtonBorderWidth = 3

Button border width (system:button-border-width)

TitlebarHeight = 4

Titlebar height (system:titlebar-height)

TitlebarButtonWidth = 5

Titlebar button area width (system:titlebar-button-width)

TitlebarPadding = 6

Implementations

impl SystemMetricRef

pub fn resolve(&self, metrics: &SystemMetrics) -> Option<PixelValue>

Resolve this system metric reference against actual system metrics.

pub fn as_css_str(&self) -> &'static str

Returns the CSS string representation of this system metric reference.

pub fn from_css_str(s: &str) -> Option<Self>

Parse a system metric reference from a CSS string (without the “system:” prefix).

Trait Implementations

impl Clone for SystemMetricRef

fn clone(&self) -> SystemMetricRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemMetricRef

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

Formats the value using the given formatter.

impl Default for SystemMetricRef

fn default() -> Self

Returns the “default value” for a type.

impl Display for SystemMetricRef

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

Formats the value using the given formatter.

impl FormatAsCssValue for SystemMetricRef

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

impl Hash for SystemMetricRef

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 SystemMetricRef

fn cmp(&self, other: &SystemMetricRef) -> 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 SystemMetricRef

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

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