Enum ConversionKind

Describes conversion between types possible during comparison.

[CompileTime]
public enum ConversionKind

Name	Description
Default	Accepts any value that is type-compatible, including boxing conversions, but excluding user-defined implicit operators. This corresponds to the behavior of C# `is` operator.
Equal	Accepts only the types that are equal, as the comparer that is being used defines equality. Unlike Identical, the names of the elements of a tuple take part, and the nullability of a reference type takes part when the comparer is IncludeNullability.
Identical	Accepts only the types between which the language defines an identity conversion. As in the language, the nullability of a reference type and the names of the elements of a tuple do not take part, so `object` and `object?`, and `(int A, int B)` and `(int, int)`, are accepted.
Implicit	Accepts any value implicitly convertible to the given type, including boxing and user-defined implicit operators. This corresponds to C# value assignability.
ImplicitReference
Reference	Accepts any value that is reference-compatible with the given type i.e. instances of subclasses or interface implementations, but refuses boxing conversions.
TypeDefinition	Accepts any value that extends or implements a type that is of the same type definition as the given type definition.
