Struct red4ext_rs::types::WeakRef

source · 
pub struct WeakRef<T: ScriptClass>(/* private fields */);
Expand description

A weak reference to a script class. Before use, it must be upgraded to a strong reference using WeakRef::upgrade.

Implementations§

source§

impl<T: ScriptClass> WeakRef<T>

source

pub fn upgrade(self) -> Option<Ref<T>>
