Macro sycamore_reactive::cloned

macro_rules! cloned {
    (($($arg : ident), *) => $e : expr) => { ... };
    ($($arg : ident), * => $e : expr) => { ... };
}

Utility macro for cloning all the arguments and expanding the expression.

Temporary workaround for Rust RFC #2407.

Example

use sycamore_reactive::*;

let state = Signal::new(0);

create_effect(cloned!((state) => move || {
   state.get();
}));

// state still accessible outside of the effect
let _ = state.get();
