Function pallet_liquidity_rewards::transactional::with_storage_layer

pub fn with_storage_layer<T, E, F>(f: F) -> Result<T, E>
where
    E: From<DispatchError>,
    F: FnOnce() -> Result<T, E>,

Execute the supplied function, adding a new storage layer.

This is the same as with_transaction, but assuming that any function returning an Err should rollback, and any function returning Ok should commit. This provides a cleaner API to the developer who wants this behavior.
