Struct MediaQuery

pub struct MediaQuery<'i> {
    pub qualifier: Option<Qualifier>,
    pub media_type: MediaType<'i>,
    pub condition: Option<MediaCondition<'i>>,
}

A media query.

Fields

qualifier: Option<Qualifier>

The qualifier for this query.

media_type: MediaType<'i>

The media type for this query, that can be known, unknown, or “all”.

condition: Option<MediaCondition<'i>>

The condition that this media query contains. This cannot have or in the first level.

Implementations

impl<'i> MediaQuery<'i>

pub fn always_matches(&self) -> bool

Returns whether the media query is guaranteed to always match.

pub fn never_matches(&self) -> bool

Returns whether the media query is guaranteed to never match.

pub fn and<'a>(&mut self, b: &MediaQuery<'i>) -> Result<(), ()>

Attempts to combine the given media query into this one. The resulting media query matches if both of the original media queries would have matched.

Returns an error if the boolean logic is not possible.

Trait Implementations

impl<'i> Clone for MediaQuery<'i>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i> Debug for MediaQuery<'i>

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

Formats the value using the given formatter.

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

fn into_owned(self) -> Self::Owned

Consumes the value and returns an owned clone.

type Owned = MediaQuery<'any>

A variant of Self with a new lifetime.

impl<'i> JsonSchema for MediaQuery<'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(generator: &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> Parse<'i> for MediaQuery<'i>

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

Parse a value of this type using an existing parser.

fn parse_string(input: &'i str) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value from a string.

impl<'i> PartialEq for MediaQuery<'i>

fn eq(&self, other: &MediaQuery<'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 MediaQuery<'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 MediaQuery<'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 MediaQuery<'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.
