Function leptos::store_value

pub fn store_value<T>(cx: Scope, value: T) -> StoredValue<T>where
    T: 'static,

Creates a non-reactive wrapper for any value by storing it within the reactive system.

Like the signal types (e.g., ReadSignal and RwSignal), it is Copy and 'static. Unlike the signal types, it is not reactive; accessing it does not cause effects to subscribe, and updating it does not notify anything else.

// this structure is neither `Copy` nor `Clone`
pub struct MyUncloneableData {
  pub value: String
}

// ❌ this won't compile, as it can't be cloned or copied into the closures
let data = MyUncloneableData { value: "a".into() };
let callback_a = move || data.value == "a";
let callback_b = move || data.value == "b";

// this structure is neither `Copy` nor `Clone`
pub struct MyUncloneableData {
  pub value: String
}

// ✅ you can move the `StoredValue` and access it with .with()
let data = store_value(cx, MyUncloneableData { value: "a".into() });
let callback_a = move || data.with(|data| data.value == "a");
let callback_b = move || data.with(|data| data.value == "b");
