Trait ContainsElement 

pub trait ContainsElement: TopologyBase {
    // Required method
    fn contains_element(&self, element: Self::ElementId) -> bool;
}

Element-ID containment capability for a topology view.

This capability answers whether an element ID is valid and visible in this view at the time of the call. It is intentionally separate from ElementIndex: an index bound is an allocation bound, while containment is an ID-validity predicate. Mutable, filtered, tombstoned, or overlay views may have indexes below the bound that are not visible elements.

Performance

Expected O(1) unless the implementation documents otherwise.

Required Methods

fn contains_element(&self, element: Self::ElementId) -> bool

Returns whether element is valid and visible in this view.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
