This commit implements Equals and GetHashCode for the ErrorOr<TValue> struct so that a deep comparison with the errors list is performed (instead of the default reference equality comparison). I introduced Microsoft.Bcl.HashCode for .NET Standard 2.0 because I did not want to reinvent the wheel for the HashCode class. If we do not want this dependency then we should copy over the source code for .NET Standard 2.0. Signed-off-by: Kenny Pflug <kenny.pflug@live.de>
This commit implements Equals and GetHashCode in the same way that the previous commit implemented it for ErrorOr<TValue>. Signed-off-by: Kenny Pflug <kenny.pflug@live.de>

This PR fixes #85 by explicitly implementing
EqualsandGetHashCodefor theErrorOr<TValue>andErrorrecord structs. In them, we perform a deep comparison for the errors list and metadata dictionary, respectively. I also include unit tests that cover these implementations.I introduced the runtime dependency Microsoft.Bcl.HashCode so that I can use the
HashCodestruct both in .NET Standard 2.0 and .NET 6. If we do not want this dependency for .NET Standard 2.0, we should copy over the source code ofHashCode- please let me know how you want to deal with this.I also introduced Nullable, but this is not a runtime dependency. It is simply there so that I can use the
MemberNotNullWhenAttributein .NET Standard 2.0, too. This helps Roslyn with tracking whether_valueor_errorsis null whenIsErrorswas called beforehand inErrorOr<TValue>.
