Enter detection on libui-rs?

[hee]

I know this is a small library, but digging through it i cant seem to find a solution for enter detection. i tried scanning for a newline char, but that didnt work, does enter even place any characters?
i wanna be able to press enter while focusing on the textbox, and have it do the same thing as submit
