Enum AtomMode 

pub enum AtomMode {
    Pin,
    Hold,
    Weak,
}

How long an atom Heap::intern returns is kept. Atoms are otherwise collected like any string: a property key, a shape, a dynamic unit or a value keeps one alive.

Variants

Pin

For the heap’s lifetime: the realm’s names and the builtins’ properties, interned while the runtime is created, and the keys of the units published before the program runs.

Hold

Until the running compilation ends: the keys, names and string constants of code compiled at run time, before its units are published and instantiated.

Weak

No longer than its holders.
