Function keeps_its_value 

Source 
fn keeps_its_value(gcx: Gcx<'_>, variable: VariableId) -> bool
Expand description

Whether the variable cannot change between the delegation and the callback guard. An intervening call can reenter and mutate a state variable after the mint reads it but before the guard does. A local, a parameter, a constant or an immutable cannot be moved that way.
