Trait SelectorQuery

pub trait SelectorQuery<E: TElement> {
    type Output;

    // Required methods
    fn should_stop_after_first_match() -> bool;
    fn append_element(output: &mut Self::Output, element: E);
    fn is_empty(output: &Self::Output) -> bool;
}

A selector query abstraction, in order to be generic over QuerySelector and QuerySelectorAll.

Required Associated Types

type Output

The output of the query.

Required Methods

fn should_stop_after_first_match() -> bool

Whether the query should stop after the first element has been matched.

fn append_element(output: &mut Self::Output, element: E)

Append an element matching after the first query.

fn is_empty(output: &Self::Output) -> bool

Returns true if the output is empty.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<E: TElement> SelectorQuery<E> for QueryAll

type Output = SmallVec<[E; 128]>

impl<E: TElement> SelectorQuery<E> for QueryFirst

type Output = Option<E>
