Functions

func NewFs

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

NewFs constructs an Fs from the path, container:path

Types

type Fs

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

Fs represents a remote yandex

func (*Fs) About

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

About gets quota information

func (*Fs) CleanUp

func (f *Fs) CleanUp(ctx context.Context) (err error)

CleanUp permanently deletes all trashed files/folders

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) CreateDir

func (f *Fs) CreateDir(ctx context.Context, path string) (err error)

CreateDir makes a directory

func (*Fs) DirMove

func (f *Fs) DirMove(ctx context.Context, src fs.Fs, srcRemote, dstRemote string) error

DirMove moves src, srcRemote to this remote at dstRemote using server-side move operations.

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

If it isn't possible then return fs.ErrorCantDirMove

If destination exists then return fs.ErrorDirExists

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) Mkdir

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

Mkdir creates the container if it doesn't exist

func (*Fs) Move

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

Move src to this remote using server-side move 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.ErrorCantMove

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 return the precision of this Fs

func (*Fs) PublicLink

func (f *Fs) PublicLink(ctx context.Context, remote string, expire fs.Duration, unlink bool) (link string, err error)

PublicLink generates a public link to the remote path (usually readable by anyone)

func (*Fs) Purge

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

Purge deletes all the files in the directory

Optional interface: Only implement this if you have a way of deleting all the files quicker than just running Remove() on the result of List()

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

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

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

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) 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

Commits the datastore

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 whether this object is 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 already existing object

Copy the reader into the object updating modTime and size.

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

type Options

type Options struct {
	Token          string               `config:"token"`
	HardDelete     bool                 `config:"hard_delete"`
	Enc            encoder.MultiEncoder `config:"encoding"`
	SpoofUserAgent bool                 `config:"spoof_ua"`
}

Options defines the configuration for this backend
