leptos-tracked

This crate provides utility traits for interacting with leptos signals.

The provided utilities provide access to standard library traits or functions without having to pass closure’s to the signals update function.

Examples

Use any of the tracked_* functions to update a mutable signal. 

use leptos::create_signal;

let (read_i32, write_i32) = create_signal(cx, 4 as i32);
let (read_bool, write_bool) = create_signal(cx, false);
let (read_str, write_str) = create_signal(cx, String::from("Hello"));
let (read_vec, write_vec) = create_signal(cx, vec![1, 2, 3]);

use leptos_tracked::MulAssign;

write_i32.tracked_mul(10);
assert_eq!(read_i32.get(), 40);

use leptos_tracked::Toggle;

write_bool.tracked_toggle();
assert_eq!(read_bool.get(), true);

use leptos_tracked::{AddAssign, Extend};

write_str.tracked_add(" ");
write_str.tracked_extend(vec!["World", "!"]);
assert_eq!(read_str.get(), "Hello World!");

use leptos_tracked::TrackedVec;

write_vec.tracked_pop();
write_vec.tracked_push(4);
assert_eq!(read_vec.get(), vec![1, 2, 4]);

write_vec.tracked_clear();
assert_eq!(read_vec.get(), vec![] as Vec<i32>);
