Module schema 

Available on crate feature turso only.

Prefixed table names and forward schema migrations.

Migrations are tracked per prefix in a {prefix}schema_version table (not PRAGMA user_version), so several finmqtt instances - or finmqtt and the caller’s own tables - can share one database without clobbering each other’s version. migrate applies every pending migration in order, each in its own transaction.

To evolve the schema, append a function to MIGRATIONS; never edit or reorder existing entries. The index of an entry is the schema version it produces (entry 0 produces version 1).

Structs

Tables 🔒

The prefix-qualified table names. Small and reused across migrations, statement preparation, and queries.

Constants

MIGRATIONS 🔒

Ordered, append-only schema migrations. Entry i advances the schema to version i + 1.

Functions

apply 🔒

Applies one migration and records its version atomically.

apply_inner 🔒

current_version 🔒

Reads the recorded schema version, or 0 if none has been recorded yet.

initial_schema 🔒

Migration v1: the live-state tables plus the per-filter subscription table.

migrate 🔒

Applies every pending migration, bringing the schema up to the latest version. A no-op once the database is current.

validate_prefix 🔒

Validates that prefix is safe to splice into table identifiers.
