pub struct MediaList<'i> {
    pub media_queries: Vec<MediaQuery<'i>>,
}

Expand description

A media query list.

Fields

media_queries: Vec<MediaQuery<'i>>

The list of media queries.

Implementations

impl<'i> MediaList<'i>

pub fn new() -> Self

Creates an empty media query list.

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

Parse a media query list from CSS.

pub fn always_matches(&self) -> bool

Returns whether the media query list always matches.

pub fn never_matches(&self) -> bool

Returns whether the media query list never matches.

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

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

Returns an error if the boolean logic is not possible.

pub fn or(&mut self, b: &MediaList<'i>)

Combines the given media query list into this one. The resulting media query list matches if either of the original media query lists would have matched.
