Types ¶
type SqlDB ¶
type SqlDB struct {
// contains filtered or unexported fields
}
pool is an atomic.Pointer, not a plain field: PoolStats (below) is read by a Prometheus scrape goroutine whose lifecycle is independent of this DB's owning service, so a scrape can legitimately race a concurrent Close.
func (*SqlDB) PoolStats ¶ added in v1.44.0
PoolStats reports pool state, the configured bounds and the acquisition counters. Unlike the other accessors it doesn't panic when the pool isn't set — ok is false instead, since a Prometheus scrape can legitimately land before connect or after Close.
type SqlTx ¶
type SqlTx struct {
// contains filtered or unexported fields
}
func (*SqlTx) BeginTx ¶ added in v1.10.0
BeginTx starts a nested transaction. pgx implements this with a SAVEPOINT, so Commit releases the savepoint and Rollback rolls back to it without affecting the enclosing transaction. Used by test helpers to give code that manages its own transactions full rollback isolation.
