Functions

func NewFs

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

NewFs makes a new Fs object from the path

The path is of the form remote:path

Remotes are looked up in the config file. If the remote isn't found then NotFoundInConfigFile will be returned.

On Windows avoid single character remote names as they can be mixed up with drive letters.

func Ptr

func Ptr[T any](t T) *T

Types

type Fs

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

Fs is the interface a cloud storage system must provide

func (*Fs) About

func (f *Fs) About(ctx context.Context) (usage *fs.Usage, err 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) CreateDir

func (f *Fs) CreateDir(ctx context.Context, pathID, leaf string) (newID string, err error)

CreateDir makes a directory with pathID as parent and name leaf

func (*Fs) DirCacheFlush

func (f *Fs) DirCacheFlush()

DirCacheFlush an optional interface to flush internal directory cache DirCacheFlush resets the directory cache - used in testing as an optional interface

func (*Fs) DirMove

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

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) FindLeaf

func (f *Fs) FindLeaf(ctx context.Context, pathID, leaf string) (pathIDOut string, found bool, err error)

FindLeaf finds a directory of name leaf in the folder with ID pathID

func (*Fs) Hashes

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

Hashes returns the supported hash types of the filesystem

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) (err error)

Mkdir makes the directory (container, bucket)

Shouldn't return an error if it already exists

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) OpenChunkWriter

func (f *Fs) OpenChunkWriter(
	ctx context.Context,
	remote string,
	src fs.ObjectInfo,
	options ...fs.OpenOption) (info fs.ChunkWriterInfo, writer fs.ChunkWriter, err error)

OpenChunkWriter returns the chunk size and a ChunkWriter

Pass in the remote and the src object You can also use options to hint at the desired chunk size

func (*Fs) Precision

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

Precision of the ModTimes in this Fs

func (*Fs) PublicLink

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

PublicLink adds a "readable by anyone with link" permission on the given file or folder.

func (*Fs) Purge

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

Purge all files in the directory specified

Implement this if you have a way of deleting all the files quicker than just running Remove() on the result of List()

Return an error if it doesn't exist

func (*Fs) Put

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

Put in to the remote path with the modTime given of the given size

When called from outside an Fs by rclone, src.Size() will always be >= 0. But for unknown-sized objects (indicated by src.Size() == -1), Put should either return an error or upload it properly (rather than e.g. calling panic).

May create the object even if it returns an error - if so will return the object and the error, otherwise will return nil and the error

func (*Fs) PutUnchecked

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

PutUnchecked uploads the object

This will create a duplicate if we upload a new file without checking to see if there is one already - use Put() for that.

func (*Fs) Rmdir

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

Rmdir removes the directory (container, bucket) if empty

Return an error if it doesn't exist or 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 returns a description of the FS

type Object

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

Object represents an teldrive 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) ID

func (o *Object) ID() string

ID returns the ID of the Object if known, or "" if not

func (*Object) MimeType

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

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) ParentID

func (o *Object) ParentID() string

ParentID implements fs.ParentIDer.

func (*Object) Remote

func (o *Object) Remote() string

Remote returns the remote path

func (*Object) Remove

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

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 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 struct {
	ApiHost           string               `config:"api_host"`
	UploadHost        string               `config:"upload_host"`
