Struct selectors::matching::StyleRelations

pub struct StyleRelations {
    // some fields omitted
}

Set of flags that determine the different kind of elements affected by the selector matching process.

This is used to implement efficient sharing.

Methods

impl StyleRelations

fn empty() -> StyleRelations

Returns an empty set of flags.

fn all() -> StyleRelations

fn from_bits_truncate(bits: u16) -> StyleRelations

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

fn intersects(&self, other: StyleRelations) -> bool

Returns true if there are flags common to both self and other.

fn contains(&self, other: StyleRelations) -> bool

Returns true all of the flags in other are contained within self.

fn insert(&mut self, other: StyleRelations)

Inserts the specified flags in-place.

fn remove(&mut self, other: StyleRelations)
