You can use from_chars, but this is such a simple and common task there should be an easy way to do it without having to work around string_view ergonomics issues.

This is a simple one-liner in just about every other language, it would look silly if the idiomatic solution in C++ was dealing with from_chars.

Not saying that you can’t do that. But the standard is big enough as it is, you don’t need to duplicate the same algorithms to the same thing in a different way.

 

<charconv> already covers almost all cases, you can use it with a view, it covers more int types than stoi/stoull family does, it covers floats.

The only thing that it doesn’t cover as a use case is buffer size estimates (which nothing in the standard does).
