Build SQLite virtual file systems (VFS) by implementing a simple Rust trait.

Documentation | Example

This library is build for my own use-case. It doesn't expose everything a SQLite VFS provides (e.g. memory mapped files). Feel free to propose additions if the current state doesn't work for your use-case.

Status

This library is still in prototype state and not ready to be used (except for maybe prototypes). While progress will be slow, it is actively worked on.

  • ✅ It passes most of SQLite's TCL test harness.
    • ⚠️ CI only runs full.test and not all.test.
    • ⚠️ Some tests are skipped.
  • ✅ Successfully runs experiments like do-sqlite.
  • ⚠️ It uses unsafe Rust, which hasn't been peer-reviewed yet.
  • ⚠️ It is not used in any production-capacity yet.

Limitations

  • WAL is not supported (but in progress)
  • Memory mapping not supported (xFetch/xUnfetch)
  • Loading extensions not supported (xDl*)
  • Tests run only on UNIX right now (due to std::os::unix usage in tests)
  • Directory sync is not supported
  • Sector size is always 1024
  • Custom device characteristic are not supported (xDeviceCharacteristics)
