	// contains filtered or unexported fields
}

Generator collects pending transactions and produces new blocks on an interval.

func New 

func New(
	c *protocol.Chain,
	s []BlockSigner,
	db pg.DB,
) *Generator

New creates and initializes a new Generator.

func (*Generator) Generate 

func (g *Generator) Generate(
	ctx context.Context,
	period time.Duration,
	health func(error),

func (g *Generator) PendingTxs() []*legacy.Tx

PendingTxs returns all of the pendings txs that will be included in the generator's next block.
