Types

type Block

type Block struct {
	block.Block
	// contains filtered or unexported fields
}

Exported for testing in avm package.

func (*Block) Accept

func (b *Block) Accept(context.Context) error

func (*Block) Reject

func (b *Block) Reject(context.Context) error

func (*Block) Verify

func (b *Block) Verify(context.Context) error

type Manager

type Manager interface {
	state.Versions

	// Returns the ID of the most recently accepted block.
	LastAccepted() ids.ID

	SetPreference(blkID ids.ID)
	Preferred() ids.ID

	GetBlock(blkID ids.ID) (snowman.Block, error)
	GetStatelessBlock(blkID ids.ID) (block.Block, error)
	NewBlock(block.Block) snowman.Block

	// VerifyTx verifies that the transaction can be issued based on the currently
	// preferred state. This should *not* be used to verify transactions in a block.
	VerifyTx(tx *txs.Tx) error

	// VerifyUniqueInputs returns nil iff no blocks in the inclusive
	// ancestry of [blkID] consume an input in [inputs].
	VerifyUniqueInputs(blkID ids.ID, inputs set.Set[ids.ID]) error
}
