Struct InitializationHandler 

pub struct InitializationHandler { /* private fields */ }

Batch DDL migration executor with tracking.

Maintains a _dbkit_migrations table so already-applied migrations are skipped on subsequent runs. Each migration is identified by a user-provided name and a content hash.

Implementations

impl InitializationHandler

pub fn new(pool: Arc<Pool>) -> Self

pub async fn run_named_migration( &self, name: &str, sql: &str, ) -> Result<(), DbkitError>

Run a named migration. Skips if already applied with the same content hash.

If the migration name exists but the hash differs, it returns an error (content changed after being applied).

pub async fn run_migrations(&self, sql: &str) -> Result<(), DbkitError>

Run migrations from a SQL string (semicolon-separated DDL statements).

This is the simple/legacy API — it runs all statements unconditionally without tracking. Use [run_named_migration] for tracked migrations.

pub async fn applied_migrations( &self, ) -> Result<Vec<(String, String, String)>, DbkitError>

List all applied migrations (name, hash, applied_at).
