Variables ¶
var Discard io.Writer = devNull(0)
Discard is an io.Writer on which all Write calls succeed without doing anything.
Functions ¶
func NopCloser ¶
func NopCloser(r io.Reader) io.ReadCloser
NopCloser returns a ReadCloser with a no-op Close method wrapping the provided Reader r.
func ReadAll ¶
ReadAll reads from r until an error or EOF and returns the data it read. A successful call returns err == nil, not err == EOF. Because ReadAll is defined to read from src until EOF, it does not treat an EOF from Read as an error to be reported.
func ReadDir ¶
ReadDir reads the directory named by dirname from the absfs.FileSystem fs and returns a list of directory entries sorted by filename.
func ReadFile ¶
func ReadFile(fs absfs.FileSystem, filename string) ([]byte, error)
ReadFile reads the file named by filename from the absfs.FileSystem fs and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.
func TempDir ¶
func TempDir(fs absfs.FileSystem, dir, prefix string) (name string, err error)
TempDir creates a new temporary directory in the directory dir of the absfs.FileSystem fs with a name beginning with prefix and returns the path of the new directory. If dir is the empty string, TempDir uses the default directory for temporary files (see os.TempDir). Multiple programs calling TempDir simultaneously will not choose the same directory. It is the caller's responsibility to remove the directory when no longer needed.
func TempFile ¶
TempFile creates a new temporary file in the directory dir of the absfs.FileSystem fs with a name beginning with prefix, opens the file for reading and writing, and returns the resulting absfs.File. If dir is the empty string, TempFile uses the default directory for temporary files for the given FileSystem (see absfs.TempDir). Multiple programs calling TempFile simultaneously will not choose the same file. The caller can use f.Name() to find the pathname of the file. It is the caller's responsibility to remove the file when no longer needed.
