Enum Modifier 

pub enum Modifier<'a> {
    Builtin {
        is_negative: bool,
        value: &'a str,
    },
    Arbitrary {
        prefix: &'a str,
        hint: &'a str,
        value: Cow<'a, str>,
    },
}

The modifier is the rest of the selector after the namespace, it is used to clarify the CSS needed to be generated.

Variants

Builtin

A builtin static modifier (e.g. bg-red-500).

Fields

is_negative: bool

Whether the value is negative (e.g. -translate-2 is negative).

value: &'a str

The inner value of the modifier.

Arbitrary

A dynamic modifier capable of automatically generating a rule from a CSS value (e.g. bg-[rgb(12_12_12)]).

All underscores in the value will be replaced by spaces except in url(), if you really want to keep one of them, you can prefix it with a backslash \_ and it will be used as is.

Sometimes the value is ambiguous, for example bg-[var(--foo)] can be handled by either the background color or the background size utility. In this case, you need to provide a CSS type hint (see the list of hints below) before the arbitrary value. For example bg-[length:var(--foo)] will generate background-size: var(--foo); (using the background size utility).

List of all type hints:

• color
• length
• line-width
• image
• url
• position
• percentage
• number
• generic-name
• family-name
• absolute-size
• relative-size
• shadow

Fields

prefix: &'a str

The rest of the modifier without the arbitrary value (e.g. bg in bg-[rgb(12_12_12)]).

hint: &'a str

The type hint needed for ambiguous values.

value: Cow<'a, str>

The inner value of the modifier.

All escaped characters (prefixed by a backslash) are already unescaped.

Trait Implementations

impl<'a> Clone for Modifier<'a>

fn clone(&self) -> Modifier<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Modifier<'a>

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

Formats the value using the given formatter.

impl<'a> Ord for Modifier<'a>

fn cmp(&self, other: &Modifier<'a>) -> 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<'a> PartialEq for Modifier<'a>

fn eq(&self, other: &Modifier<'a>) -> 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<'a> PartialOrd for Modifier<'a>

fn partial_cmp(&self, other: &Modifier<'a>) -> 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.
