Trait Implementations

impl Clone for CssValue

fn clone(&self) -> CssValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CssValue

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

Formats the value using the given formatter.

impl Display for CssValue

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

Formats the value using the given formatter.

impl From<&str> for CssValue

fn from(value: &str) -> Self

Converts to this type from the input type.

fn from(value: Angle) -> Self

Converts to this type from the input type.

impl From<Color> for CssValue

fn from(value: Color) -> Self

Converts to this type from the input type.

impl From<Length> for CssValue

fn from(value: Length) -> Self

Converts to this type from the input type.

impl PartialEq for CssValue

fn eq(&self, other: &CssValue) -> 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.
