Struct wasmtime_runtime::StoreBox

pub struct StoreBox<T: ?Sized>(_);

A Box<T> lookalike for memory that’s stored in a Store<T>

This is intended to be quite similar to a Box<T> except without the Deref implementations. The main motivation for this type’s existence is to appease the aliasing rules in miri to ensure that StoreBox can be moved around without invalidating pointers to the contents within the box. The standard Box<T> type does not implement this for example and moving that will invalidate derived pointers.

Implementations
