TODO: remove pointers when upgrading to gormv2 which has https://github.com/go-gorm/gorm/issues/2748 fixed.

func (*OffchainReportingOracleSpec) BeforeCreate 

func (s *OffchainReportingOracleSpec) BeforeCreate(db *gorm.DB) error

func (*OffchainReportingOracleSpec) BeforeSave 

func (s *OffchainReportingOracleSpec) BeforeSave(db *gorm.DB) error

func (OffchainReportingOracleSpec) GetID 

func (s OffchainReportingOracleSpec) GetID() string

func (*OffchainReportingOracleSpec) SetID 

func (s *OffchainReportingOracleSpec) SetID(value string) error

func (OffchainReportingOracleSpec) TableName 

func (OffchainReportingOracleSpec) TableName() string

type PipelineRun 

type PipelineRun struct {
	ID int64 `json:"-" gorm:"primary_key"`
}

func (PipelineRun) GetID 

func (pr PipelineRun) GetID() string

func (*PipelineRun) SetID 

func (pr *PipelineRun) SetID(value string) error

type Service 

type Service interface {
	Start() error
	Close() error
}

type Spawner 

type Spawner interface {
	Start() error
	Close() error
	CreateJob(ctx context.Context, spec Job, name null.String) (int32, error)
	DeleteJob(ctx context.Context, jobID int32) error
}

The job spawner manages the spinning up and spinning down of the long-running services that perform the work described by job specs. Each active job spec has 1 or more of these services associated with it.

At present, Flux Monitor and Offchain Reporting jobs can only have a single "initiator", meaning that they only require a single service. But the older "direct request" model allows for multiple initiators, which imply multiple services.

type SpecError 

type SpecError struct {
	ID          int64 `gorm:"primary_key"`
	JobID       int32
	Description string
	Occurrences uint
	CreatedAt   time.Time
	UpdatedAt   time.Time
}

func (SpecError) TableName 

func (SpecError) TableName() string

type Type 

type Type string
const (
	DirectRequest     Type = "directrequest"
	FluxMonitor       Type = "fluxmonitor"
	OffchainReporting Type = "offchainreporting"
	Keeper            Type = "keeper"
)
