Generational Box
Generational Box is a runtime for Rust that allows any static type to implement Copy. It can be combined with a global runtime to create an ergonomic state solution like dioxus-signals. This crate doesn't have any unsafe code.
Three main types manage state in Generational Box:
Store: Handles recycling generational boxes that have been dropped. Your application should have one store or one store per thread.Owner: Handles dropping generational boxes. The owner acts like a runtime lifetime guard. Any states that you create with an owner will be dropped when that owner is dropped.GenerationalBox: The core Copy state type. The generational box will be dropped when the owner is dropped.
Example:
use generational_box::{UnsyncStorage, AnyStorage};
// Create an owner for some state for a scope
let owner = UnsyncStorage::owner();
// Create some non-copy data, move it into a owner, and work with copy data
let data: String = "hello world".to_string();
let key = owner.insert(data);
// The generational box can be read from and written to like a RefCell
let value = key.read();
assert_eq!(*value, "hello world");
How it works
Internally, generational-box creates an arena of generational RefCells that are recycled when the owner is dropped. You can think of the cells as something like &'static RefCell<Box<dyn Any>> with a generational check to make recycling a cell easier to debug. Then GenerationalBoxes are Copy because the &'static pointer is Copy.
