Derive Macro LiftSync 

#[derive(LiftSync)]

Derive macro to lift a struct into a thread-safe reactive SignalSync.

Applying #[derive(LiftSync)] to a struct generates an inner unwrapped struct and a lift(self) method that produces a crate::signal_sync::SignalSync<'a, _Inner> where any fields of type SignalSync<'a, T> are replaced by their inner T in the generated inner struct. The generated lift method wires up thread-safe reactions so that changes to any signal fields propagate into the resulting lifted SignalSync.

Example:

use crate::signal_sync::SignalSync;

#[derive(LiftSync)]
struct ExampleSync<'a> {
    a: SignalSync<'a, i32>,
    b: String,
}

let example = ExampleSync { a: SignalSync::new(1), b: "hi".to_string() };
let lifted = example.lift(); // SignalSync<'a, _ExampleSync>
lifted.with(|inner| println!("a = {}", inner.a));
