Functions

func GetPerm

func GetPerm(beacon []byte, runtimeID common.Namespace, rngCtx []byte, nrNodes int) ([]int, error)

GetPerm generates a permutation that we use to choose nodes from a list of eligible nodes to elect.

func New

func New() api.Application

New constructs a new scheduler application instance.

Types

type Query

type Query interface {
	Validators(context.Context) ([]*scheduler.Validator, error)
	AllCommittees(context.Context) ([]*scheduler.Committee, error)
	KindsCommittees(context.Context, []scheduler.CommitteeKind) ([]*scheduler.Committee, error)
	Genesis(context.Context) (*scheduler.Genesis, error)
	ConsensusParameters(context.Context) (*scheduler.ConsensusParameters, error)
}

Query is the scheduler query interface.

type QueryFactory

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

QueryFactory is the scheduler query factory.

func NewQueryFactory

func NewQueryFactory(state abciAPI.ApplicationQueryState) *QueryFactory

NewQueryFactory returns a new QueryFactory backed by the given state instance.

func (*QueryFactory) QueryAt

func (sf *QueryFactory) QueryAt(ctx context.Context, height int64) (Query, error)

QueryAt returns the scheduler query interface for a specific height.
