gen_range is not able to generate 255 for an u8 type (also applies for other types) #1002
Comments
You could use |
It does work for my use case since it covers the whole number range, however it wouldn't work if I wanted anything smaller such as [10, 255]. |
|
Oh, I see. I'd like to help! Either approach would avoid issues like mine I guess. |
This was fixed with #1003, you can now use |
I'm currently developing a chip8 emulator as a learning experience and one of the instructions requires the generation of a random number between 0 and 255 (inclusive).
I am using
u8
types to represent the number, currently the following code will not compile.I understand that 256 is outside the range of
u8
, however this makes it impossible to generate 255.Bellow I provide a simple example which does not compile.
I'd say that a possible fix would be to provide a function which is inclusive, but I have no idea of possible challenges.
Thank you for your time!
