RecordSet identifies a type that holds a set of records of a given model.

type SQLParams 

type SQLParams []interface{}

An SQLParams is a list of parameters that are passed to the DB server with the query string and that will be used in the placeholders.

func (SQLParams) Extend 

func (p SQLParams) Extend(p2 SQLParams) SQLParams

Extend returns a new SQLParams with both params of this SQLParams and of p2 SQLParams.

type Sequence 

type Sequence struct {
	JSON      string
	Increment int64
	Start     int64
	// contains filtered or unexported fields
}

A Sequence holds the metadata of a DB sequence

There are two types of sequences: those created before bootstrap and those created after. The former will be created and updated at bootstrap and cannot be modified afterwards. The latter will be created, updated or dropped immediately.

func CreateSequence 

func CreateSequence(name string, increment, start int64) *Sequence

CreateSequence creates a new Sequence in the database and returns a pointer to it

func (*Sequence) Alter 

func (s *Sequence) Alter(increment, restart int64)

Alter alters this sequence by changing next number and/or increment. Set a parameter to 0 to leave it unchanged.

func (*Sequence) Drop 

func (s *Sequence) Drop()

Drop this sequence and removes it from the database

func (*Sequence) NextValue 

func (s *Sequence) NextValue() int64

NextValue returns the next value of this Sequence

type WorkerFunction added in v0.0.39 

type WorkerFunction interface {
	// Run the worker function
	Run()
	// LoopPeriod is the time between each run of the worker function
	LoopPeriod() time.Duration
}

A WorkerFunction can be executed in a loop in background every given LoopPeriod.

func NewWorkerFunction added in v0.0.39 

func NewWorkerFunction(fnct func(), period time.Duration) WorkerFunction

NewWorkerFunction returns a WorkerFunction from the given fnct and period
