Enum ElementMergeStrategy 

pub enum ElementMergeStrategy {
    ReplaceElements,
    AppendElements,
    UnionElements,
}

Strategy for merging the children (elements) of a pattern.

Variants

ReplaceElements

Later element list completely replaces earlier ones.

AppendElements

Concatenate all element lists in traversal order.

UnionElements

Deduplicate elements by identity.

Trait Implementations

impl Clone for ElementMergeStrategy

fn clone(&self) -> ElementMergeStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElementMergeStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ElementMergeStrategy

fn eq(&self, other: &ElementMergeStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
