A css value.

Variants

Bang(String)

A special kind of escape. Only really used for !important.

Call(String, CallArgs)

An function call that was not evaluated.

Function(String, Option<SassFunction>)

A (callable?) function.

Literal(String, Quotes)

List(Vec<Value>, ListSeparator, bool)

A comma- or space separated list of values, with or without brackets.

Numeric(Number<isize>, Unit, bool)

A Numeric value is a rational value with a Unit (which may be Unit::None) and flags.

The boolean flag is true for calculated values and false for literal values.

NumericBig(Number<BigInt>, Unit, bool)

A rational value with a Unit and flags, similar to Numeric, but with support for arbitrarily large numbers.

Color(Rgba, Option<String>)

Null

True

False

BinOp(Box<Value>, bool, Operator, bool, Box<Value>)

A binary operation, two operands and an operator. The booleans represents possible whitespace.

UnaryOp(Operator, Box<Value>)

Map(OrderMap<Value, Value>)

UnicodeRange(String)

A unicode range for font selections. U+NN, U+N?, U+NN-MM. The string is the entire value, including the "U+" tag.

Paren(Box<Value>)

Implementations

impl Value

pub fn scalar<T: Into<Number<isize>>>(v: T) -> Self

pub fn bool(v: bool) -> Self

pub fn black() -> Self

pub fn rgba(r: Rational, g: Rational, b: Rational, a: Rational) -> Self

pub fn hsla(h: Rational, s: Rational, l: Rational, a: Rational) -> Self

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

pub fn is_calculated(&self) -> bool

pub fn into_calculated(self) -> Self

pub fn is_true(&self) -> bool

All values other than False and Null should be considered true.

pub fn is_null(&self) -> bool

pub fn integer_value(&self) -> Result<isize, Error>

pub fn unquote(self) -> Value

pub fn iter_items(self) -> Vec<Value>

pub fn format(&self, format: Format) -> Formatted<'_, Value>

Get a reference to this Value bound to an output format.

The bound referene implements Display, so it can be written with the rust format!(...) macros or coverted with the to_string()` method.

Example

assert_eq!(
    Value::scalar(42).format(Default::default()).to_string(),
    "42",
);

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Eq for Value

impl Ord for Value

fn cmp(&self, other: &Value) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Value> for Value

Some Values are equal according to spec even with some implementation differences.

fn eq(&self, other: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Value> for Value

fn partial_cmp(&self, other: &Value) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Value) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Value) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Value) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Value) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
