Enum DbPool 

pub enum DbPool {
    Sqlite(SqlitePool),
    Postgres(PgPool),
}

A pool of database connections, typed by backend.

Cloning is cheap — both variants wrap an Arc-backed inner pool, so a clone() just bumps the refcount.

Variants

Sqlite(SqlitePool)

SQLite-backed connection pool. The default through Phase 1 and the only variant the queryset / migration engine accepts today.

Postgres(PgPool)

Postgres-backed connection pool. Connectable at Phase 1, but any code path that calls into the queryset or migration engine against this variant panics with a clear “arrives in Phase 2” message. The seam itself is the deliverable here.

Implementations

impl DbPool

pub fn as_sqlite(&self) -> Option<&SqlitePool>

Borrow the inner SqlitePool. Returns None for a Postgres pool. Phase 1 callers that haven’t migrated to the dispatch API yet typically reach for Self::sqlite_or_panic; the returned-Option variant is for the (rare today) code that wants to gracefully fall back.

pub fn as_postgres(&self) -> Option<&PgPool>

Borrow the inner PgPool. Returns None for a SQLite pool.

pub fn sqlite_or_panic(&self) -> &SqlitePool

Borrow the inner SqlitePool, panicking with a clear “Postgres support arrives in Phase 2” message on a Postgres variant. Used by pool and pool_for so existing plugin code (that expects a SqlitePool) doesn’t quietly limp along when the operator connects to Postgres.

pub fn backend_name(&self) -> &'static str

The string identifier of the underlying backend. Matches crate::backend::DatabaseBackend::name for the active pool variant.
