Struct warp_contracts_core::optional_cell::OptionalCell

pub struct OptionalCell<T> {
    pub cell: RefCell<Option<T>>,
}

Tiny wrapper over RefCell that:

• allow for uninitialized values (by storing Option)
• allow static usage (by implementing Sync and providing const constructor)

Because WASM is single threaded, we don’t need to worry much about inter-thread communication

Fields

cell: RefCell<Option<T>>
