StoreShallowEqualityComparer

Remarks

For a selector returning a list, where a fresh instance of the same elements should not read as a change: UseStore(store, s => s.Items, StoreShallowEqualityComparer.Sequence<Item>()). A selector returning a tuple or a value-type record needs no comparer — UseStore<TStore, TSel>(Store<TStore>, Func<TStore, TSel>, IEqualityComparer<TSel>?) documents which selector shapes its default already answers for.

Methods

Sequence<T>()

Returns a comparer that treats two System.Collections.Generic.IReadOnlyList<T> as equal when their lengths match and each element pair is Object.is-equal: reference identity for reference types (strings compare by ordinal value instead), bit-pattern equality for float/double, and boxed value equality for other value types. A fresh-but-value-equal reference-type element (other than a string) therefore counts as changed.
