Struct style::invalidation::media_queries::EffectiveMediaQueryResults

pub struct EffectiveMediaQueryResults {
    set: FxHashSet<MediaListKey>,
}

A struct that holds the result of a media query evaluation pass for the media queries that evaluated successfully.

Fields

set: FxHashSet<MediaListKey>

The set of media lists that matched last time.

Implementations

impl EffectiveMediaQueryResults

pub fn new() -> Self

Trivially constructs an empty EffectiveMediaQueryResults.

pub fn clear(&mut self)

Resets the results, using an empty key.

pub fn was_effective<T>(&self, item: &T) -> bool

where T: ToMediaListKey,

Returns whether a given item was known to be effective when the results were cached.

pub fn saw_effective<T>(&mut self, item: &T)

where T: ToMediaListKey,

Notices that an effective item has been seen, and caches it as matching.

Trait Implementations

impl Clone for EffectiveMediaQueryResults

fn clone(&self) -> EffectiveMediaQueryResults

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EffectiveMediaQueryResults

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

Formats the value using the given formatter.

impl MallocSizeOf for EffectiveMediaQueryResults

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

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for EffectiveMediaQueryResults

fn eq(&self, other: &EffectiveMediaQueryResults) -> 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.
