A database with SQLite

Project overview · Compiled explanation

Sequences

Call arrows identify checked targets; loop and branch frames determine when they run. Open that target’s module to follow its implementation. Branches describe alternatives; loops describe repeated work. Native calls and interface dispatch stop at their declared contracts. Exit notes end that path; enclosing recovery and cleanup remain visible.

storedName

Source

Store a bound value in an in-memory SQLite database and read it back.

Failures can raise SqliteError.
