Functions

func SanityCheckLocalConfig

func SanityCheckLocalConfig(c types.LocalConfig) (err error)

Types

type Bootstrapper

type Bootstrapper struct {
	// contains filtered or unexported fields
}

Bootstrapper connects to a particular feed and listens for config changes, but does not participate in the protocol. It merely acts as a bootstrap node for peer discovery.

func NewBootstrapper

func NewBootstrapper(args BootstrapperArgs) (*Bootstrapper, error)

func (*Bootstrapper) Close

func (b *Bootstrapper) Close() error

Close shuts down a Bootstrapper. Can safely be called multiple times.

func (*Bootstrapper) Start

func (b *Bootstrapper) Start() error

Start spins up a Bootstrapper.

OCR2OracleArgs contains the configuration and services a caller must provide, in order to run the offchainreporting protocol.

type Oracle

type Oracle struct {
	// contains filtered or unexported fields
}

func NewOracle

func NewOracle(args OracleArgs) (*Oracle, error)

NewOracle returns a newly initialized Oracle using the provided services and configuration.

func (*Oracle) Close

func (o *Oracle) Close() error

Close shuts down an oracle. Can safely be called multiple times.

func (*Oracle) Start

func (o *Oracle) Start() error

Start spins up a Oracle.

type OracleArgs

type OracleArgs interface {
	// contains filtered or unexported methods
}
