Methods

pub const RESTYLE_CSS_TRANSITIONS: RestyleHint

RESTYLE_CSS_TRANSITIONS: RestyleHint = RestyleHint{bits: 1 << 4,}

pub const RESTYLE_STYLE_ATTRIBUTE: RestyleHint

RESTYLE_STYLE_ATTRIBUTE: RestyleHint = RestyleHint{bits: 1 << 6,}

Don't re-run selector-matching on the element, only the style attribute has changed, and this change didn't have any other dependencies.

pub const RESTYLE_SMIL: RestyleHint

RESTYLE_SMIL: RestyleHint = RestyleHint{bits: 1 << 7,}

pub fn has_animation_hint(&self) -> bool

Returns whether the hint specifies that an animation cascade level must be replaced.

pub fn has_animation_hint_or_recascade(&self) -> bool

Returns whether the hint specifies that an animation cascade level must be replaced.

pub fn has_non_animation_hint(&self) -> bool

Returns whether the hint specifies some restyle work other than an animation cascade level replacement.

pub fn match_self(&self) -> bool

Returns whether the hint specifies that selector matching must be re-run for the element.

pub fn has_replacements(&self) -> bool
