type Event

type Event struct {
	ID              string
	Op              Op
	Query           string
	Args            []string

type Op

type Op int32

Op represents the type of database operation captured.

const (
	OpQuery    Op = iota // Simple query or extended-query execute
	OpExec               // Non-query execution
	OpPrepare            // Prepared statement parse
	OpBind               // Parameter binding
	OpExecute            // Extended-protocol execute
	OpBegin              // Transaction begin
	OpCommit             // Transaction commit
	OpRollback           // Transaction rollback
)

func (Op) String

func (o Op) String() string

type Proxy

type Proxy interface {
	// ListenAndServe accepts client connections and relays them to the upstream DB.
	ListenAndServe(ctx context.Context) error
	// Events returns the channel of captured events.
	Events() <-chan Event
	// Close stops the proxy.
	Close() error
}
