pub enum CalcExpr {
    Length(Box<Length>),
    Number(Box<Number>),
    Angle(Box<Angle>),
    Plus(Box<CalcExpr>, Box<CalcExpr>),
    Sub(Box<CalcExpr>, Box<CalcExpr>),
    Mul(Box<CalcExpr>, Box<CalcExpr>),

Variants

Length(Box<Length>)

A length, e.g. 2px.

Number(Box<Number>)

A number, e.g. 0.1.

Angle(Box<Angle>)

An angle, e.g. 45deg.

Plus(Box<CalcExpr>, Box<CalcExpr>)

+ expression.

Sub(Box<CalcExpr>, Box<CalcExpr>)

- expression.

Mul(Box<CalcExpr>, Box<CalcExpr>)

* expression.

Div(Box<CalcExpr>, Box<CalcExpr>)

/ expression.

Implementations

impl CalcExpr

pub fn resolve_length<L: LengthNum>( &self, media_query_status: &MediaQueryStatus<L>, relative_length: L, ) -> Option<L>

Resolve the length value to L.

The relative_length is used to calculate ...% length. The base font size in media_query_status is used for em length.

impl CalcExpr

pub fn is_number(&self) -> bool

Check if the expression is a number.

pub fn get_number(&self) -> Option<&Number>

Get the number value if the expression is a number.

pub fn is_zero(&self) -> bool

Check if the expression is a static number 0.

pub fn is_specified_value(&self) -> bool

Check if the expression is a literal value, a.k.a. does not contain any operator.

pub fn mul_div(&self, rhs: f32, mul: bool) -> Self

Multiply rhs if mul is true; divide rhs otherwise.

Trait Implementations

impl Clone for CalcExpr

fn clone(&self) -> CalcExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CalcExpr

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

Formats the value using the given formatter.

impl Default for CalcExpr

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CalcExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CalcExpr

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

Formats the value using the given formatter.

impl PartialEq for CalcExpr

fn eq(&self, other: &CalcExpr) -> 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 Serialize for CalcExpr

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
