Types

type Attr

type Attr struct {
	Inode  uint64      // inode number
	Size   uint64      // size in bytes
	Atime  time.Time   // time of last access
	Mtime  time.Time   // time of last modification
	Ctime  time.Time   // time of last inode change
	Crtime time.Time   // time of creation (OS X only)
	Mode   os.FileMode // file mode
	Nlink  uint32      // number of links (usually 1)
	Uid    uint32      // owner uid
	Gid    uint32      // group gid
	Flags  uint32      // chflags(2) flags (OS X only)
}

An Attr is the metadata for a single file or directory.

type CopyOperation

type CopyOperation struct {
	*Operation

	Source string

}

CopyOperation - Copy source object to target.

type File

type File struct {
