4//! [`RuntimeObjectResolver`] adapter.
5//!
6//! `RuntimeObjectResolver` is one of the supertrait bounds on
7//! [`sui_types::storage::RpcStateReader`]. Its methods feed the
8//! Move runtime's dynamic-field / receive-object paths. **This
9//! adapter is read-only and does not serve Move execution**: it
10//! returns `Ok(None)` from both methods.
11//!
12//! Callers that need execution-time child-object resolution
13//! (re-running a transaction, simulating dry-runs) should keep
14//! using the validator perpetual store — this adapter is meant
15//! for the read-only RPC surface where child-object lookups never
16//! arise.
