Struct jlrs::wrappers::ptr::value::LeakedValue

pub struct LeakedValue(_);

While jlrs generally enforces that Julia data can only exist and be used while a frame is active, it’s possible to leak global values: Symbols, Modules, and globals defined in those modules.

Implementations

impl LeakedValue

pub unsafe fn as_value<'scope>(
    self,
    _: Global<'scope>
) -> Value<'scope, 'static>

Convert this LeakedValue back to a Value. This requires a Global, so this method can only be called inside a closure taken by one of the scope-methods.

Safety: you must guarantee this value has not been freed by the garbage collector. While Symbols are never garbage collected, modules and their contents can be redefined.
