tests/cases/conformance/types/typeRelationships/typeInference/genericCallWithObjectTypeArgs.ts(20,9): error TS2453: The type argument for type parameter 'T' cannot be inferred from the usage. Consider specifying the type arguments explicitly.
|
|
Type argument candidate 'C' is not a valid type argument because it is not a supertype of candidate 'D'.
|
|
Types have separate declarations of a private property 'x'.
