Functions ¶
func Asset ¶
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 ¶
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 ¶
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.
