pub fn init_sqlite()Expand description
Ensures sqlite3mc’s global codec registration is complete before any test body runs.
sqlite3mc registers its cipher implementations the first time
sqlite3_open_v2 is called. When the test binary runs all tests in
parallel threads, two threads can race inside that one-time
initialization and one of them sees an “unknown cipher ‘chacha20’”
error even though chacha20 is compiled in.
Calling this at the start of every test ensures exactly one thread
performs the first open (all others block on the OnceLock) so that
by the time any test-specific code runs, sqlite3mc is fully initialized.
§Panics
Panics if sqlite3mc cannot open an in-memory database.
