Performs copy-assignment from source.

impl Debug for HierarchyEvent

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

Formats the value using the given formatter.

impl PartialEq<HierarchyEvent> for HierarchyEvent

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

This method tests for self and other values to be equal, and is used by ==.

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