Exception in doc

I do not like the word "Exception" here, because Rust doesn't have the term exception in its library, in contrast to other languages, e.g. C#, Java, C++, ...

The Rust documentation ueses the word "Panics" when it will panic under certain conditions (e.g. u32::overflowing_div).

I would suggest to adopt the phrasing.

You're right that "Exception" probably isn't the correct phrasing. However, those items listed under "Exceptions" are conditions that, when met, will cause the function to return an Err and not directly cause a panic. Perhaps rephrasing to "Errors" would be the most appropriate?

[hellow554]

Errors sounds fine to me.

You want to rephrase the next sentence then to

An error will be returned if

Great! Thank you for the issue @hellow554!
