Sergey Bugaev 135d29b498 AK: Assert that we don't create StringViews of negative length 
Due to us using size_t for the length, the actual value will always be positive.
If, for example, we calculate the length as "0 - 1", we'll get SIZE_T_MAX. What
we can do is check that adding the characters pointer and the length together
doesn't overflow.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Travis CI status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
