Trait Element 

pub trait Element: Sized {
    // Required methods
    fn parent_element(&self) -> Option<Self>;
    fn prev_sibling_element(&self) -> Option<Self>;
    fn has_local_name(&self, name: &str) -> bool;

}

A trait to query an element node metadata.

Required Methods

fn parent_element(&self) -> Option<Self>

Returns a parent element.

fn prev_sibling_element(&self) -> Option<Self>

Returns a previous sibling element.

fn has_local_name(&self, name: &str) -> bool

Checks that the element has a specified local name.

fn attribute_matches( &self, local_name: &str, operator: AttributeOperator<'_>, ) -> bool

Checks that the element has a specified attribute.

fn pseudo_class_matches(&self, class: PseudoClass<'_>) -> bool

Checks that the element matches a specified pseudo-class.

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.
