Function use_context

pub fn use_context<T>() -> Option<T>
where
    T: Clone + 'static,

Try to retrieve a stored Context value in the reactive system. You can store a Context value anywhere, and retrieve it from anywhere afterwards.

Example

In a parent component:

provide_context(42);
provide_context(String::from("Hello world"));

And so in a child component you can retrieve each context data by specifying the type:

let foo: Option<i32> = use_context();
let bar: Option<String> = use_context();
