Trait selectors::parser::SelectorImpl [−] [src]

pub trait SelectorImpl: Clone + Sized + 'static {
    type AttrValue: Clone + Eq + for<'a> From<&'a str> + Display;
    type Identifier: Clone + Eq + for<'a> From<&'a str> + Display + PrecomputedHash;
    type ClassName: Clone + Eq + for<'a> From<&'a str> + Display + PrecomputedHash;
    type LocalName: Clone + Eq + for<'a> From<&'a str> + Display + Borrow<Self::BorrowedLocalName> + PrecomputedHash;
    type NamespaceUrl: Clone + Eq + Default + Borrow<Self::BorrowedNamespaceUrl> + PrecomputedHash;
    type NamespacePrefix: Clone + Eq + for<'a> From<&'a str> + Display + Default;
    type BorrowedNamespaceUrl: ?Sized + Eq;
    type BorrowedLocalName: ?Sized + Eq;
    type NonTSPseudoClass: Clone + Eq + Sized + ToCss + SelectorMethods<Impl = Self>;
    type PseudoElement: Clone + Eq + PseudoElement<Impl = Self>;
    fn is_active_or_hover(pseudo_class: &Self::NonTSPseudoClass) -> bool;
}

This trait allows to define the parser implementation in regards of pseudo-classes/elements

NB: We need Clone so that we can derive(Clone) on struct with that are parameterized on SelectorImpl. See https://github.com/rust-lang/rust/issues/26925

Associated Types

non tree-structural pseudo-classes (see: https://drafts.csswg.org/selectors/#structural-pseudos)

pseudo-elements

Required Methods

Returns whether the given pseudo class is :active or :hover.
