Implementations

impl MediaFeatureValue

pub const fn is_number(&self) -> bool

Returns true if self is of variant Number.

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

Returns Some if self is a reference of variant Number, and None otherwise.

Returns Some if self is a mutable reference of variant Number, and None otherwise.

pub fn expect_number(self) -> Number

where Self: Debug,

Unwraps the value, yielding the content of Number.

Panics

Panics if the value is not Number, with a panic message including the content of self.

Trait Implementations

impl Clone for MediaFeatureValue

fn clone(&self) -> MediaFeatureValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MediaFeatureValue

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

Formats the value using the given formatter.

impl EqIgnoreSpan for MediaFeatureValue

fn eq_ignore_span(&self, other: &Self) -> bool

impl From<Dimension> for MediaFeatureValue

fn from(v: Dimension) -> Self

Converts to this type from the input type.

impl From<Function> for MediaFeatureValue

fn from(v: Function) -> Self

Converts to this type from the input type.

impl From<Ident> for MediaFeatureValue

fn from(v: Ident) -> Self

Converts to this type from the input type.
