An implementation of IComparer<T> and IEqualityComparer<T> to compare IReadOnlyKey instances.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

    interface IEqualityComparer<IKey>
    interface IComparer<IKey>

Fields

Instance

The singleton instance of the comparer to use.

Methods

Compare(IKey, IKey)	Compares two objects and returns a value indicating whether one is less than, equal to, or greater than the other.
Compare(IReadOnlyKey, IReadOnlyKey)	Compares two objects and returns a value indicating whether one is less than, equal to, or greater than the other.
Equals(IKey, IKey)	Determines whether the specified objects are equal.
Equals(IReadOnlyKey, IReadOnlyKey)	Determines whether the specified objects are equal.
GetHashCode(IKey)	Returns a hash code for the specified object.
GetHashCode(IReadOnlyKey)	Returns a hash code for the specified object.
