Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo added in v0.20.0

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func BuildTx

func BuildTx(appState *appstate.AppState, from common.Address, to *common.Address, txType types.TxType,
	amount decimal.Decimal, maxFee decimal.Decimal, tips decimal.Decimal, nonce uint32, epoch uint16,
	payload []byte) *types.Transaction

func ConvertToFloat

func ConvertToFloat(amount *big.Int) decimal.Decimal

func ConvertToInt

func ConvertToInt(amount decimal.Decimal) *big.Int

func MustAsset added in v0.20.0

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func NewTiming

func NewTiming(conf *config.ValidationConfig) *timing

func RestoreAsset added in v0.20.0

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets added in v0.20.0

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively
