Function magnus::gc::mark_movable

pub fn mark_movable<T>(value: T) where
    T: Deref<Target = Value>, 

Available on ruby_gte_2_7 only.

Mark an Object and let Ruby know it is moveable.

The Value type is effectly a pointer to a Ruby object. Ruby’s garbage collector will avoid moving objects exposed to extensions, unless you use this function to mark them during the GC marking phase.

Used to mark any stored Ruby objects when implementing DataTypeFunctions::mark and you have also implemented DataTypeFunctions::compact.

Beware that any Ruby object passed to this function may later become invalid to use from Rust when GC is run, you must update any stored objects with location inside your implementation of DataTypeFunctions::compact.
