use_max

Reactive max().

Works with any container that implements IntoIterator (Vec, HashSet, ...) with any elements that implement PartialOrd and Clone (floats, ints, strings, ...).

If the container is empty or only contains non comparable values like NaN, it returns None. Otherwise it returns the Some(<largest value>) in the container.

Usage

use leptos::prelude::*;
use leptos_use::math::use_max;

#[component]
fn Demo() -> impl IntoView {
let (values, set_values) = signal(vec![1.0, 2.0, 3.0, f32::NAN, 4.0, 5.0]);
let result = use_max::<Vec<f32>, _, _>(values); // Some(5.0)

assert_eq!(result.get(), Some(5.0));
view! { }
}

Feature
