* feat: Implement `get_transaction_depth` for drivers
* test: Verify `get_transaction_depth()` on postgres
* Refactor: `TransactionManager` delegation without BC
SQLite implementation is currently WIP
* Fix: Avoid breaking changes on `AnyConnectionBackend`
* Refactor: Remove verbose `SqliteConnection` typing
* Feat: Implementation for SQLite
I have included `AtomicUsize` in `WorkerSharedState`. Ideally, it is not desirable to execute `load` and `fetch_add` in two separate steps, but we decided to allow it here since there is only one thread writing. To prevent writing from other threads, the field itself was made private, and a getter method was provided with `pub(crate)`.
* Refactor: Same approach for `cached_statements_size`
ref: a66787d36d62876b55475ef2326d17bade817aed
* Fix: Add missing `is_in_transaction` for backend
* Doc: Remove verbose "synchronously" word
* Fix: Remove useless `mut` qualifier
* feat: add Connection::begin_with
This patch completes the plumbing of an optional statement from these methods to
`TransactionManager::begin` without any validation of the provided statement.
There is a new `Error::InvalidSavePoint` which is triggered by any attempt to
call `Connection::begin_with` when we are already inside of a transaction.
* feat: add Pool::begin_with and Pool::try_begin_with
* feat: add Error::BeginFailed and validate that custom "begin" statements are successful
* chore: add tests of Error::BeginFailed
* chore: add tests of Error::InvalidSavePointStatement
* chore: test begin_with works for all SQLite "BEGIN" statements
* chore: improve comment on Connection::begin_with
* feat: add default impl of `Connection::begin_with`
This makes the new method a non-breaking change.
* refactor: combine if statement + unwrap_or_else into one match
* feat: use in-memory SQLite DB to avoid conflicts across tests run in parallel
* feedback: remove public wrapper for sqlite3_txn_state
Move the wrapper directly into the test that uses it instead.
* fix: cache Status on MySqlConnection
* fix: compilation errors
* fix: format
* fix: postgres test
* refactor: delete `Connection::get_transaction_depth`
* fix: tests
