The following code compiles with a warning (on take function):

function cannot return without recursing
a loop may express intention better if this is on purpose

use std::ops::Deref;

pub trait MutexGuard<T>: Deref<Target = T> /*+ DerefMut<Target = T>*/ {
    fn set(&mut self, value: T);
    fn take(&self) -> Option<T>;
}

impl<T> MutexGuard<T> for tokio::sync::MutexGuard<'_, T> {
    fn set(&mut self, value: T) {
        *self.deref_mut() = value;
    }

    fn take(&self) -> Option<T> {
        tokio::sync::MutexGuard::take(self)
    }
}

Is there any way to make it work without renaming take? I also don’t understand why the current version does not work (I specified the “full path” to the function tokio::sync::MutexGuard::take. Why does Rust use a trait instead?)
