Functions ¶
func RandomBytes ¶
RandomBytes returns a byte array of the given size with random values.
Types ¶
type TestBlockChain ¶
type TestBlockChain struct {
GenisisNode ipld.Node
GenisisLink ipld.Link
MiddleNodes []ipld.Node
MiddleLinks []ipld.Link
TipNode ipld.Node
TipLink ipld.Link
// contains filtered or unexported fields
}
TestBlockChain is a simulated data structure similar to a blockchain
func SetupBlockChain ¶
func SetupBlockChain( ctx context.Context, t testing.TB, lsys ipld.LinkSystem, size uint64, blockChainLength int) *TestBlockChain
SetupBlockChain creates a new test block chain with the given height
func (*TestBlockChain) AllBlocks ¶
func (tbc *TestBlockChain) AllBlocks() []blocks.Block
AllBlocks returns all blocks for a blockchain
func (*TestBlockChain) Blocks ¶
func (tbc *TestBlockChain) Blocks(from int, to int) []blocks.Block
Blocks Returns the given raw blocks for the block chain for the given range, indexed from the tip
func (*TestBlockChain) Chooser ¶
func (tbc *TestBlockChain) Chooser(ipld.Link, ipld.LinkContext) (ipld.NodePrototype, error)
Chooser is a NodeBuilderChooser function that always returns the block chain
func (*TestBlockChain) LinkTipIndex ¶

LinkTipIndex returns a link to the block at the given index from the tip
func (*TestBlockChain) NodeTipIndex ¶
func (tbc *TestBlockChain) NodeTipIndex(fromTip int) ipld.Node
NodeTipIndex returns the node to the block at the given index from the tip
func (*TestBlockChain) PathTipIndex ¶
func (tbc *TestBlockChain) PathTipIndex(fromTip int) ipld.Path
PathTipIndex returns the path to the block at the given index from the tip
func (*TestBlockChain) RemainderBlocks ¶
func (tbc *TestBlockChain) RemainderBlocks(from int) []blocks.Block
RemainderBlocks returns the remaining blocks for a blockchain, indexed from tip
func (*TestBlockChain) Selector ¶
func (tbc *TestBlockChain) Selector() ipld.Node
Selector returns the selector to recursive traverse the block chain parent links
