Enum DbPool 

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

A database connection pool — either SQLite or PostgreSQL.

DbPool is the primary database handle threaded through atrg’s AppState. It is cheaply cloneable (the underlying sqlx pools are themselves Arc-based).

Variants

Sqlite(SqlitePool)

A SQLite connection pool. Available when the sqlite cargo feature is enabled (the default).

Postgres(PgPool)

A PostgreSQL connection pool. Available when the postgres cargo feature is enabled.

Implementations

impl DbPool

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

Borrow the inner SQLite pool, if any.

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

Borrow the inner PostgreSQL pool, if any.

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

Returns a static string identifying the backend kind: "sqlite" or "postgres". Useful for diagnostics and tests.

pub async fn close(&self)

Close the pool, waiting for in-flight queries to complete.

pub fn is_closed(&self) -> bool

Whether the underlying pool has been closed.

pub async fn ping(&self) -> Result<()>

Run a trivial SELECT 1 round-trip against the pool; used by the /readyz health endpoint.
