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::*;
use leptos_use::math::use_max;
#[component]
fn Demo() -> impl IntoView {
let (values, set_values) = create_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! { }
}
