## Purpose of this PR
- Implement open function
- Add basic structure for the following
- exception handling
- testing using gradle
## Changes
- Java
- Remove unnecessary example code(Connection.java, Cursor.java,
Limbo.java)
- Implement `open`
- Add exception handling logic
- Add junit test
- Rust
- Add limbo_db.rs which implements native functions defined in
`Limbo.java`
- Remove unnecessary example code in lib.rs
## TODOS
- Implement core features for AbstractDB.java and LimboDB.java (I'm
currently referencing sqlite-java, but there are some minor differences
as we use rust instead of C)
## Reference
- https://github.com/tursodatabase/limbo/issues/615Closes#632
Lots of cleanup still left to do. Draft PR for adding support for OPFS
for WASM build (add support for limbo in browser).
Overall explanation of the architecture: this follows the sqlite wasm
architecture for OPFS.
main <> (limbo-worker.js) limbo (VFS - opfs.js) <> opfs-sync-proxy
The main thread loads limbo-worker.js which bootstraps the opfs.js and
opfs-sync-proxy.js and then launches the limbo-wasm.js.
At that point it can be used with worker.postmessage and
worker.onmessage interactions from the main thread.
The VFS provided by opfs.js provides a sync API by offloading async
operations to opfs-sync-proxy.js. This is done through SharedArrayBuffer
and Atomic.wait() to make the actual async operations appear synchronous
for limbo.

#514
Introduces a new feature for lazy evaluation in the
`Statement.raw().iterate()` method and includes related changes in both
the test and implementation files. The most important changes include
adding a test case for lazy evaluation, creating a `RowIterator` struct,
and modifying the `iterate` method to use this new struct.
Everything seems to works fine, but suggestions on code improvement and
test use cases are welcoming.
Closes#527
The name "row result" is confusing because it really *is* a result from
a step() call. The only difference is how a row is represented as we
return from VDBE or from a statement.
Therefore, rename RowResult to StepResult.
The only instances of the &(*x) dereferencing pattern in the codebase,
is used with Completion smart pointers. Changed it to use as_ref(). No
functional changes.
Closes#516
Somehow the `make` command does not work because of the name
mismatching. This PR will fix only this issue.
For reproducing the issue:
```
$ make

## Another issue...
`maturin` is still not in requirements dev list. Shall we continue to
install it manually or add it to dev list?
Closes#495
