The resulting equality context handles null values appropriately:
Two null values are considered equal
A null value and a non-null value are considered not equal
Two non-null values are compared using this equality context
Receiver
The equality context for non-nullable elements.
Return
An Equality instance that can handle nullable elements.
Type Parameters
The non-nullable element type for which to create a nullable equality context.
Returns a Hashing context for nullable elements based on this non-nullable hashing context.
The resulting hashing context handles null values by returning 0 for null, and delegates to this hashing context for non-null values.
Receiver
The hashing context for non-nullable elements.
Return
A Hashing instance that can handle nullable elements.
Type Parameters
The non-nullable element type for which to create a nullable hashing context.
