ExperimentalStableMemory.stableVarQueryfor estimating stable variable storage requirements during upgradeReturns a query that, when called, returns the number of bytes of (real) IC stable memory that would be occupied by persisting its current stable variables before an upgrade.
This function may be used to monitor or limit real stable memory usage.
The query computes the estimate by running the first half of an upgrade, including any
preupgradesystem method.Like any other query, its state changes are discarded so no actual upgrade (or other state change) takes place.
The query can only be called by the enclosing actor and will trap for other callers.
