This PR was created with heavy assistance from Cursor Tab (an AI-assisted IDE). The workflow with that IDE is that you make a change, then the IDE goes "Oh, so you probably also want to change this line? And this line?" and you go tab-tab-tab as it proposes successive line edits. I tried to make sure all the changes were signature-only and didn't affect program behavior, but I might have let some slip. I'll try to double-check again later in the day. |

All tests except doc tests passed on the first try, so that's encouraging. |

Yeah, documentation is very WIP. |

Basically, previous code was using
WidgetMut<MyWidget>as a receiver. This can be done when WidgetMut is a local type, but external users wouldn't be able to do it. The result would be that users importing Masonry as a dependency but copy-pasting code from one of our widgets would get compile errors.This PR switches to a syntax that external crates will be able to use when declaring widgets. It's a more verbose, less readable syntax, but it's unambiguous and doesn't require clever tricks.
We can consider switching back to WidgetMut-as-a-receiver when
#![feature(arbitrary_self_types)]or some equivalent gets stabilized. See rust-lang/rust#44874 (comment) for current progress.
