Types

type Mgr

type Mgr interface {
	// New creates a new State object, for the purposes of executing
	// queries within a single context.
	New() State
}

Mgr manages the initialisation of transaction state objects. Mgr instances may exist in multiple goroutines.

type State

type State interface {
	WithTxn(fn func() error) error
	InTxn() bool
	ResetTxn() error
}

State represents the transaction state for a single request. A State object instance should exist only within a single goroutine. It MUST NOT be shared between goroutines.
