§type Value = &'hook SharedStateEq<T>
type Value = &'hook SharedStateEq<T>
The output type of
Hook::use_hook. Read moresource§fn replace_mut<F: FnOnce(&mut T) -> T>(&self, f: F) -> T
fn replace_mut<F: FnOnce(&mut T) -> T>(&self, f: F) -> T
Always notify the value is changed
because the caller can mutate the value inside f.
To notify changes only when new_value != old_value,
use replace_from_ref or
self.inner().map_mut_and_notify_if()
instead.

fn replace_with<F: FnOnce(&T) -> T>(&self, f: F) -> T
The old value is returned.
