Types ¶
type FileSystem ¶
type FileSystem struct {
// contains filtered or unexported fields
}
FileSystem is an implementation of the sandbox.FileSystem interface backed by a tarball.
func Open ¶
func Open(data io.ReaderAt, size int64) (*FileSystem, error)
Open creates a file system from the tarball represented by the given section.
The file system retains the io.ReaderAt as a backing storage layer, it does not load the content of the files present in the tarball in memory; only the structure of the file system is held in memory (e.g. directory paths and metadata about the files).
func OpenFile ¶
func OpenFile(f *os.File) (*FileSystem, error)
OpenFile is like Open but it takes an *os.File opened on a tarball as argument.
The file must remain open for as long as the program needs to access the file system.
func (*FileSystem) Filesize ¶
func (fsys *FileSystem) Filesize() int64
Filesize returns the size occupied by the file data in the file system.
func (*FileSystem) Memsize ¶
func (fsys *FileSystem) Memsize() int64
Memsize returns the size occupied by the file system in memory.
func (*FileSystem) Open ¶
func (fsys *FileSystem) Open(name string, flags sandbox.OpenFlags, mode fs.FileMode) (sandbox.File, error)
Open satisfies sandbox.FileSystem.
func (*FileSystem) Size ¶
func (fsys *FileSystem) Size() int64
Size returns the size of data in the file system, which is the value passed to Open when fsys was created. It is the full size of the underlying tarball.
