Relative Lengths

unit	relative to
em	font size of element
ex	x-height of element’s font
ch	width of the “0” (ZERO, U+0030) glyph in the element’s font
rem	font size of the root element
vw	1% of viewport’s width
vh	1% of viewport’s height
vmin	1% of viewport’s smaller dimension
vmax	1% of viewport’s larger dimension

Others

unit	represents
dpi	Dots per inch
dpcm	Dots per centmeter

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl Default for Unit

fn default() -> Unit

Returns the “default value” for a type.

impl FromStr for Unit

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Unit, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Unit

fn cmp(&self, _: &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.

impl PartialEq for Unit

fn eq(&self, o: &Self) -> 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 Unit

fn partial_cmp(&self, _: &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.

impl ToString for Unit

fn to_string(&self) -> String

Converts the given value to a String.

impl Copy for Unit

impl Eq for Unit
