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.

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> ParseWithOptions<'i> for MediaQuery<'i>

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

Parse a value of this type with the given options.

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

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

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl<'i> Serialize for MediaQuery<'i>

Available on crate feature serde only.

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

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

Available on crate feature visitor only.

const CHILD_TYPES: VisitTypes

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>

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>
