…rage snapshots
Implements ContractStorageExporter which reads all persistent and
temporary storage entries for a given Soroban contract via
SorobanRpc.Server.getLedgerEntries(), deserialises ScVal keys and
values to typed ScValJson objects, and exports them as a typed JSON
ContractStorageSnapshot.
New files:
- src/diagnostics/ContractStorageExporter.ts
- ContractStorageSnapshot, StorageEntry, StorageDiff types
- ScValJson union type covering i128, u64, bool, str, vec, map,
address and all other ScVal variants
- ContractStorageExporter class with export(), diff(), fromJson()
- scValToJson() helper exported for direct use
- src/diagnostics/DiagnosticEventsParser.ts
- DiagnosticEvent type and re-exports ScValJson
Updated:
- src/index.ts — exports ContractStorageExporter, scValToJson and
all related types from the package root
Tests (test/diagnostics/ContractStorageExporter.test.ts, 39 tests):
- empty contract returns zero entries
- persistent and temporary entries combined
- ScVal types: void, bool, i32, u32, i64, u64, i128, str, sym,
address, vec, map, nested structures
- diff() correctly identifies added, removed, and modified entries
across all three categories simultaneously
- JSON round-trip preserves bigint-encoded-as-string values (i128,
u64 max) and expiresAt metadata
