Enum UnitlessZeroResolves 

pub enum UnitlessZeroResolves {
    Length,
    Number,
}

How unitless zero (0 without a unit) resolves in a given context.

For most Style Values, a 0 can be a drop-in replacement for 0px, but certain style values will provide discrete syntax for 0px and 0, meaning they resolve to different things. For properties that accept both <number> and <length>, unitless zero may resolve to a different value. Using a piece of metadata to describe this can be helpful for linting/minifying - avoiding a reduction in semantic meaning.

Examples:

• width: 0px == width: 0 (unitless zero resolves to length)
• line-height: 0px != line-height: 0 (unitless zero resolves to number = 0x multiplier)
• tab-size: 0px != tab-size: 0 (unitless zero resolves to number = 0 tab characters)

Variants

Length

Unitless zero resolves to a length (0 = 0px).

Number

Unitless zero resolves to a number or percentage. NOT safe to reduce.

Trait Implementations

impl Clone for UnitlessZeroResolves

fn clone(&self) -> UnitlessZeroResolves

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnitlessZeroResolves

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

impl Default for UnitlessZeroResolves

fn default() -> UnitlessZeroResolves

Returns the “default value” for a type.

impl Hash for UnitlessZeroResolves

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,

impl Ord for UnitlessZeroResolves

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

impl PartialEq for UnitlessZeroResolves

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

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