Functions

func NewFs

func NewFs(name, root string) (fs.Fs, error)

NewFs contstructs an FsStorage from the path, bucket:path

Types

type FsObjectStorage

type FsObjectStorage struct {
	// contains filtered or unexported fields
}

FsObjectStorage describes a storage object

Will definitely have info but maybe not meta

func (*FsObjectStorage) Fs

func (o *FsObjectStorage) Fs() fs.Fs

Return the parent Fs

func (*FsObjectStorage) Md5sum

func (o *FsObjectStorage) Md5sum() (string, error)

Md5sum returns the Md5sum of an object returning a lowercase hex string

func (*FsObjectStorage) ModTime

func (o *FsObjectStorage) ModTime() time.Time

ModTime returns the modification time of the object

It attempts to read the objects mtime and if that isn't present the LastModified returned in the http headers

func (*FsObjectStorage) Open

func (o *FsObjectStorage) Open() (in io.ReadCloser, err error)

Open an object for read

func (*FsObjectStorage) Remote

func (o *FsObjectStorage) Remote() string

Return the remote path

func (*FsObjectStorage) Remove

func (o *FsObjectStorage) Remove() error

Remove an object

func (*FsObjectStorage) SetModTime

func (o *FsObjectStorage) SetModTime(modTime time.Time)

Sets the modification time of the local fs object

func (*FsObjectStorage) Size

func (o *FsObjectStorage) Size() int64

Size returns the size of an object in bytes

func (*FsObjectStorage) Storable

func (o *FsObjectStorage) Storable() bool

Is this object storable

func (*FsObjectStorage) String

func (o *FsObjectStorage) String() string

Return a string version

func (*FsObjectStorage) Update

func (o *FsObjectStorage) Update(in io.Reader, modTime time.Time, size int64) error

Update the object with the contents of the io.Reader, modTime and size

The new object may have been created if an error is returned

type FsStorage

type FsStorage struct {
	// contains filtered or unexported fields
}

FsStorage represents a remote storage server

func (*FsStorage) Copy

func (f *FsStorage) Copy(src fs.Object, remote string) (fs.Object, error)

Copy src to this remote using server side copy operations.

This is stored with the remote path given

It returns the destination Object and a possible error

Will only be called if src.Fs().Name() == f.Name()

If it isn't possible then return fs.ErrorCantCopy

func (*FsStorage) List

func (f *FsStorage) List() fs.ObjectsChan

Walk the path returning a channel of FsObjects

func (*FsStorage) ListDir

func (f *FsStorage) ListDir() fs.DirChan

Lists the buckets

func (*FsStorage) Mkdir

func (f *FsStorage) Mkdir() error

Mkdir creates the bucket if it doesn't exist

func (*FsStorage) Name

func (f *FsStorage) Name() string

The name of the remote (as passed into NewFs)

func (*FsStorage) NewFsObject

func (f *FsStorage) NewFsObject(remote string) fs.Object

Return an FsObject from a path

May return nil if an error occurred

func (*FsStorage) Precision

func (fs *FsStorage) Precision() time.Duration

Return the precision

func (*FsStorage) Put

func (f *FsStorage) Put(in io.Reader, remote string, modTime time.Time, size int64) (fs.Object, error)

Put the object into the bucket

Copy the reader in to the new object which is returned

The new object may have been created if an error is returned

func (*FsStorage) Rmdir

func (f *FsStorage) Rmdir() error

Rmdir deletes the bucket

Returns an error if it isn't empty: Error 409: The bucket you tried to delete was not empty.

func (*FsStorage) Root

func (f *FsStorage) Root() string

The root of the remote (as passed into NewFs)

func (*FsStorage) String

func (f *FsStorage) String() string

String converts this FsStorage to a string
