Struct SqliteAdapter 

pub struct SqliteAdapter { /* private fields */ }

Implementations

impl SqliteAdapter

pub fn open(path: &str) -> Result<Self, StorageError>

Open or create a SQLite database at the given path.

pub fn in_memory() -> Result<Self, StorageError>

Create an in-memory SQLite database.

impl SqliteAdapter

pub fn plan_from_live( &self, target: &AppManifest, ) -> Result<SchemaPlan, StorageError>

Plan schema changes by comparing the live DB state against the target manifest. Only plans additive operations: CreateEntity, AddField, AddIndex.

impl SqliteAdapter

pub fn apply_with_history( &self, plan: &SchemaPlan, meta: &PushMetadata<'_>, ) -> Result<(), StorageError>

Apply a schema plan and record the push in the history table — atomically. If either the DDL or the history INSERT fails, the whole transaction rolls back so the database never ends up with a schema change that has no history row, or a history row that points at a failed migration.

pub fn read_history( &self, limit: Option<u32>, ) -> Result<Vec<HistoryEntry>, StorageError>

Read schema push history, newest-first. Returns empty vec if the history table does not exist.

pub fn read_history_entry( &self, entry_id: &str, ) -> Result<Option<HistoryEntry>, StorageError>

Read a single history entry by ID. Returns None if the history table doesn’t exist or the ID is not found.

impl SqliteAdapter

pub fn read_schema(&self) -> Result<SchemaSnapshot, StorageError>

Read the current schema from the live SQLite database. Only inspects user tables (not sqlite_* internal tables).

Trait Implementations

impl StorageAdapter for SqliteAdapter

fn plan_schema(&self, target: &AppManifest) -> Result<SchemaPlan, StorageError>

Produce a plan that would bring storage in line with the target manifest.

fn apply_schema(&self, plan: &SchemaPlan) -> Result<(), StorageError>

Apply a schema plan. Not implemented by dry-run adapters.
