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
