# always-assert
Recoverable assertions, inspired by [the use of `assert()` in SQLite](https://www.sqlite.org/assert.html).
```rust
use always_assert::never;
fn apply_transaction(&mut self, tx: Transaction) -> Result<(), TransactionAborted> {
let delta = self.compute_delta(&tx);
if never!(!self.check_internal_invariant(&delta)) {
// Ok, something in this transaction messed up our internal state.
// This really shouldn't be happening, and this signifies a bug.
// Luckily, we can recover by just rejecting the transaction.
return abort_transaction(tx);
}
self.commit(delta);
Ok(())
}
```
