Enum Comparison

pub enum Comparison {
    LessThan(Lt),
    GreaterThan(Gt),
    GreaterThanEqual(GreaterThanEqual),
    LessThanEqual(LessThanEqual),
    Equal(Eq),
}

This enum represents a set of comparison operators, used in Ranged Media Features (see RangedFeature), and could be used in other parts of a CSS-alike language. This isn’t a strictly standard part of CSS, but is provided for convenience.

Comparison is defined as:

<comparison>
 │├──╮─ "="  ─╭──┤│
     ├─ "<"  ─┤
     ├─ "<=" ─┤
     ├─ ">"  ─┤
     ╰─ ">=" ─╯

Variants

LessThan(Lt)

GreaterThan(Gt)

GreaterThanEqual(GreaterThanEqual)

LessThanEqual(LessThanEqual)

Equal(Eq)

Trait Implementations

impl Clone for Comparison

fn clone(&self) -> Comparison

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Comparison

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

Formats the value using the given formatter.

impl Hash for Comparison

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 Comparison

fn cmp(&self, other: &Comparison) -> 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> Parse<'a> for Comparison

fn parse(p: &mut Parser<'a>) -> Result<Comparison>

fn try_parse(p: &mut Parser<'a>) -> Result<Self>

impl PartialEq for Comparison

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

fn partial_cmp(&self, other: &Comparison) -> 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 Serialize for Comparison

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToCursors for Comparison

fn to_cursors(&self, s: &mut impl CursorSink)

impl Copy for Comparison

impl Eq for Comparison

impl StructuralPartialEq for Comparison
