struct SomeNum {

Python's chr() and ord() in Rust
In Python you can convert an integer into a character and a character into an integer with ord() and chr():
>>>a = "a"
>>>b = ord(a) + 1
>>>b = chr(b)
I am looking for a way to do the same thing in Rust, but I have found nothing similar yet.

python how to compute a simple checksum as quickly as zlib.adler32
I wish to compute a simple checksum : just adding the values of all bytes.
The quickest way I found is:
checksum = sum([ord(c) for c in buf])
But for 13 Mb data buf, it takes 4.4 s : too long (in C, it takes 0.5 s)
If I use :
checksum =…
