Deserialization errors
data DeserializationError #
Constructors
| DeserializationErrorMalformed String | Malformed JSON has syntax errors in the JSON itself (i.e., we cannot even parse it to a JSValue) |
| DeserializationErrorSchema String | Invalid JSON has valid syntax but invalid structure The string gives a hint about what we expected instead |
| DeserializationErrorUnknownKey KeyId | The JSON file contains a key ID of an unknown key |
| DeserializationErrorValidation String | Some verification step failed |
| DeserializationErrorFileType String String | Wrong file type Records actual and expected types. |

54-bit integer values
JavaScript can only safely represent numbers between -(2^53 - 1) and
2^53 - 1.
TODO: Although we introduce the type here, we don't actually do any bounds
checking and just inherit all type class instance from Int64. We should
probably define fromInteger to do bounds checking, give different instances
for type classes such as Bounded and FiniteBits, etc.
