Struct ImmutableGroup 

pub struct ImmutableGroup<T, K, G> { /* private fields */ }

The state of a group at one moment (ImmutableGroup<TObject, TKey, TGroupKey>, the IGrouping of the change sets of GroupWithImmutableState): a copy of its items that does not change. A clone is the same state.

Deviation (DEVIATIONS.md, DynamicData): upstream’s class is internal and its change sets hold the interface IGrouping; here they hold this type, so it is public.

Implementations

impl<T: Clone, K: Eq + Hash + Clone, G> ImmutableGroup<T, K, G>

pub fn ptr_eq(&self, other: &Self) -> bool

Whether self and other are the same state (ReferenceEquals).
