Make Sized optional in FromHex trait #25

Closed loriopatrick closed 5 years ago

Better supports fixed types such as [u8; 32] by allowing the compiler to determine the data type's size.

Looks like the compiler doesn't support this feature.... huh. Going to do some local testing.

It's ?Sized not Sized?. Though I'm not sure what you are trying to achieve with this change exactly. Even with : ?Sized it wouldn't compile as the only method returns Self by value which is only allowed when Self is Sized.
