Enum Expression

pub enum Expression {
    Method(String, Vec<Expression>),
    Complex(Vec<Expression>),
    Number(Number, String),
    Color(Color),
    Other(String),
}

This object represents an expression used to define something. E.g. brushes are defined using an expression in there themes definition.

Variants

Implementations

impl Expression

Try to convert self into a Number

pub fn color(&self) -> Option<Color>

pub fn relative_dir(&self) -> Option<RelativeDir>

pub fn angle(&self) -> Option<Angle>

pub fn css_gradient(&self) -> Option<Gradient>

pub fn brush(&self) -> Option<Brush>

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Default for Expression

fn default() -> Self

Returns the “default value” for a type.

impl From<&str> for Expression

fn from(s: &str) -> Expression

Converts to this type from the input type.

impl From<Expression> for Number

fn from(e: Expression) -> Self

Converts to this type from the input type.

impl From<String> for Expression

fn from(s: String) -> Expression

Converts to this type from the input type.

impl PartialEq for Expression

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

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