Implementations

impl<'i> MediaFeatureValue<'i>

pub fn parse<'t>( input: &mut Parser<'i, 't>, expected_type: MediaFeatureType, ) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parses a single media query feature value, with an expected type. If the type is unknown, pass MediaFeatureType::Unknown instead.

Trait Implementations

impl<'i> Clone for MediaFeatureValue<'i>

fn clone(&self) -> MediaFeatureValue<'i>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i> Debug for MediaFeatureValue<'i>

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

Formats the value using the given formatter.

impl<'de: 'i, 'i> Deserialize<'de> for MediaFeatureValue<'i>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'any, 'i> IntoOwned<'any> for MediaFeatureValue<'i>

fn into_owned(self) -> Self::Owned

Consumes the value and returns an owned clone.

type Owned = MediaFeatureValue<'any>

A variant of Self with a new lifetime.

impl<'i> JsonSchema for MediaFeatureValue<'i>

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl<'i> PartialEq for MediaFeatureValue<'i>

fn eq(&self, other: &MediaFeatureValue<'i>) -> 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<'i> Serialize for MediaFeatureValue<'i>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'i> ToCss for MediaFeatureValue<'i>

fn to_css<W>( &self, dest: &mut Printer<'_, '_, '_, W>, ) -> Result<(), PrinterError>

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string( &self, options: PrinterOptions<'_>, ) -> Result<String, PrinterError>

Serialize self in CSS syntax and return a string.

impl<'i, __T: Visit<'i, __T, __V>, __V: ?Sized + Visitor<'i, __T>> Visit<'i, __T, __V> for MediaFeatureValue<'i>

const CHILD_TYPES: VisitTypes

Available on crate feature visitor only.

The types of values contained within this value and its children. This is used to skip branches that don’t have any values requested by the Visitor.

fn visit(&mut self, visitor: &mut __V) -> Result<(), __V::Error>

Available on crate feature visitor only.

Visits the value by calling an appropriate method on the Visitor. If no corresponding visitor method exists, then the children are visited.

fn visit_children(&mut self, visitor: &mut __V) -> Result<(), __V::Error>

Available on crate feature visitor only.

Visit the children of this value.
