Methods

impl Expression

pub fn kind_for_testing(&self) -> &ExpressionKind

The kind of expression we're, just for unit testing.

Eventually this will become servo-only.

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

Parse a media expression of the form:

(media-feature: media-value)

Only supports width and width ranges for now.

pub fn matches(&self, device: &Device, quirks_mode: QuirksMode) -> bool

Evaluate this expression and return whether it matches the current device.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

This method tests for !=.

impl MallocSizeOf for Expression

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
