WithLogger configures logger.

func WithPath

func WithPath(path string) GenOpt

WithPath configures path for persistent databases.

func WithSeed

func WithSeed(seed int64) GenOpt

func WithStates

func WithStates(n int) GenOpt

WithStates creates n states.

type Generator

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

Generator for layers of blocks.

func New

func New(opts ...GenOpt) *Generator

New creates Generator instance.

func (*Generator) GetState

func (g *Generator) GetState(i int) State

GetState at index.

func (*Generator) Layer

func (g *Generator) Layer(i int) *types.Layer

Layer returns generated layer.

func (*Generator) Merge

func (g *Generator) Merge(other *Generator)

Merge other Generator state into this Generator state.

func (*Generator) Next

func (g *Generator) Next(opts ...NextOpt) types.LayerID

Next generates the next layer.

func (*Generator) Setup

func (g *Generator) Setup(opts ...SetupOpt)

Setup should be called before running Next.

func (*Generator) Split

func (g *Generator) Split(opts ...SplitOpt) []*Generator

Split generator into multiple partitions. First generator will use original tortoise state (mesh, activations).

type NextOpt

type NextOpt func(*nextConf)

NextOpt is for configuring layer generator.

func WithBlockTickHeights

func WithBlockTickHeights(heights ...uint64) NextOpt

WithBlockTickHeights updates height of the blocks.

func WithCoin

func WithCoin(coin bool) NextOpt

WithCoin is to setup weak coin for voting. By default coin will support blocks.

func WithEmptyHareOutput

func WithEmptyHareOutput() NextOpt

WithEmptyHareOutput will save an empty vector for hare output.

func WithHareOutputIndex

func WithHareOutputIndex(i int) NextOpt

WithHareOutputIndex sets the index of the block that will be stored as a hare output.

func WithLayerSizeOverwrite

func WithLayerSizeOverwrite(size int) NextOpt

WithLayerSizeOverwrite overwrite expected layer size.

func WithNextReorder

func WithNextReorder(delay uint32) NextOpt

WithNextReorder configures when reordered layer should be returned. Examples: Next() Next(WithNextReorder(1)) Next() 1 3 2 Next() Next(WithNextReorder(2)) Next() Next() 1 3 4 2

So the Next layer with WithNextReorder will be delayed exactly by `delay` value.

func WithNumBlocks

func WithNumBlocks(num int) NextOpt

WithNumBlocks sets number of the generated blocks.

func WithVoteGenerator

func WithVoteGenerator(gen VotesGenerator) NextOpt

WithVoteGenerator declares vote generator for a layer.

func WithoutHareOutput

func WithoutHareOutput() NextOpt

WithoutHareOutput will prevent from saving hare output.

type Sequence

type Sequence struct {
	Length int
	Opts   []NextOpt
}

Sequence of layers with same configuration.

func WithSequence

func WithSequence(lth int, opts ...NextOpt) Sequence

WithSequence creates Sequence object.

type SetupOpt

type SetupOpt func(g *setupConf)

SetupOpt configures setup.

func WithSetupMinerRange

func WithSetupMinerRange(low, high int) SetupOpt

WithSetupMinerRange number of miners will be selected between low and high values.

func WithSetupTicks

func WithSetupTicks(ticks ...uint64) SetupOpt

WithSetupTicks configures ticks for every atx.

func WithSetupTicksRange

func WithSetupTicksRange(low, high int) SetupOpt

WithSetupTicksRange configures range of atxs, that will be randomly chosen by atxs.

func WithSetupUnitsRange

func WithSetupUnitsRange(low, high int) SetupOpt

WithSetupUnitsRange adjusts units of the ATXs, which will directly affect block weight.

type SplitOpt

type SplitOpt func(*splitConf)

SplitOpt is for configuring partition.

func WithPartitions
