package mobile

import "robpike.io/ivy/mobile"

The mobile package provides a very narrow interface to ivy, suitable for wrapping in a UI for mobile applications. It is designed to work well with the gomobile tool by exposing only primitive types. It's also handy for testing.

TODO: This package (and ivy itself) has global state, so only one execution stream (Eval or Demo) can be active at a time.
