When doing streaming uploads (eg using rcat or mount) setting this

This will limit the maximum upload size to 5GB. However non chunked
files are easier to deal with and have an MD5SUM.

Rclone will still chunk files bigger than chunk_size when doing normal
copy operations.`,

SharedOptions are shared between swift and hubic

Functions

func NewFs

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

NewFs constructs an Fs from the path, container:path

func NewFsWithConnection

func NewFsWithConnection(opt *Options, name, root string, c *swift.Connection, noCheckContainer bool) (fs.Fs, error)

NewFsWithConnection constructs an Fs from the path, container:path and authenticated connection.

if noCheckContainer is set then the Fs won't check the container exists before creating it.

Types

type Fs

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

Fs represents a remote swift server

func (*Fs) About

func (f *Fs) About(ctx context.Context) (*fs.Usage, error)

About gets quota information

func (*Fs) Copy

func (f *Fs) Copy(ctx context.Context, 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 (*Fs) Features

func (f *Fs) Features() *fs.Features

Features returns the optional features of this Fs

func (*Fs) Hashes

func (f *Fs) Hashes() hash.Set

Hashes returns the supported hash sets.

func (*Fs) List

func (f *Fs) List(ctx context.Context, dir string) (entries fs.DirEntries, err error)

List the objects and directories in dir into entries. The entries can be returned in any order but should be for a complete directory.

dir should be "" to list the root, and should not have trailing slashes.

This should return ErrDirNotFound if the directory isn't found.

func (*Fs) ListR

func (f *Fs) ListR(ctx context.Context, dir string, callback fs.ListRCallback) (err error)

ListR lists the objects and directories of the Fs starting from dir recursively into out.

dir should be "" to start from the root, and should not have trailing slashes.

This should return ErrDirNotFound if the directory isn't found.

It should call callback for each tranche of entries read. These need not be returned in any particular order. If callback returns an error then the listing will stop immediately.

Don't implement this unless you have a more efficient way of listing recursively than doing a directory traversal.

func (*Fs) Mkdir

func (f *Fs) Mkdir(ctx context.Context, dir string) error

Mkdir creates the container if it doesn't exist

func (*Fs) Name

func (f *Fs) Name() string

Name of the remote (as passed into NewFs)

func (*Fs) NewObject

func (f *Fs) NewObject(ctx context.Context, remote string) (fs.Object, error)

NewObject finds the Object at remote. If it can't be found it returns the error fs.ErrorObjectNotFound.

func (*Fs) Precision

func (f *Fs) Precision() time.Duration

Precision of the remote

func (*Fs) Purge

func (f *Fs) Purge(ctx context.Context) error

Purge deletes all the files and directories

Implemented here so we can make sure we delete directory markers

func (*Fs) Put

func (f *Fs) Put(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) (fs.Object, error)

Put the object into the container

Copy the reader in to the new object which is returned

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

func (*Fs) PutStream

func (f *Fs) PutStream(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) (fs.Object, error)

PutStream uploads to the remote path with the modTime given of indeterminate size

func (*Fs) Rmdir

func (f *Fs) Rmdir(ctx context.Context, dir string) error

Rmdir deletes the container if the fs is at the root

Returns an error if it isn't empty

func (*Fs) Root

func (f *Fs) Root() string

Root of the remote (as passed into NewFs)

func (*Fs) String

func (f *Fs) String() string

String converts this Fs to a string

type Object

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

Object describes a swift object

Will definitely have info but maybe not meta

func (*Object) Fs

func (o *Object) Fs() fs.Info

Fs returns the parent Fs

func (*Object) Hash

func (o *Object) Hash(ctx context.Context, t hash.Type) (string, error)

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

func (*Object) MimeType

func (o *Object) MimeType(ctx context.Context) string

MimeType of an Object if known, "" otherwise

func (*Object) ModTime

func (o *Object) ModTime(ctx context.Context) 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 (*Object) Open

func (o *Object) Open(ctx context.Context, options ...fs.OpenOption) (in io.ReadCloser, err error)

Open an object for read

func (*Object) Remote

func (o *Object) Remote() string

Remote returns the remote path

func (*Object) Remove

func (o *Object) Remove(ctx context.Context) (err error)

Remove an object

func (*Object) SetModTime

func (o *Object) SetModTime(ctx context.Context, modTime time.Time) error

SetModTime sets the modification time of the local fs object

func (*Object) Size

func (o *Object) Size() int64

Size returns the size of an object in bytes

func (*Object) Storable

func (o *Object) Storable() bool

Storable returns if this object is storable

It compares the Content-Type to directoryMarkerContentType - that makes it a directory marker which is not storable.

func (*Object) String

func (o *Object) String() string

Return a string version

func (*Object) Update

func (o *Object) Update(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) 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 Options

type Options struct {
	EnvAuth                     bool                 `config:"env_auth"`
	User                        string               `config:"user"`
