This section is empty.


func NewFs

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

NewFs constructs an Fs from the path


type Fs

type Fs struct {
	// contains filtered or unexported fields

Fs represents a local filesystem rooted at root

func (*Fs) About

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

About gets quota information

func (*Fs) Command added in v1.50.20

func (f *Fs) Command(ctx context.Context, name string, arg []string, opt map[string]string) (interface{}, error)

Command the backend to run a named command

The command run is name args may be used to read arguments from opts may be used to read optional arguments from

The result should be capable of being JSON encoded If it is a string or a []string it will be shown to the user otherwise it will be JSON encoded and shown to the user like that

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 directory 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 ErrorObjectNotFound.

func (*Fs) OpenWriterAt added in v1.6.1

func (f *Fs) OpenWriterAt(ctx context.Context, remote string, size int64) (fs.WriterAtCloser, error)

OpenWriterAt opens with a handle for random access writes

Pass in the remote desired and the size if known.

It truncates any existing object

func (*Fs) Precision

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

Precision of the file system

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 to the local filesystem

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 removes the directory

If it isn't empty it will return an error

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 represents a local filesystem 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, r hash.Type) (string, error)

Hash returns the requested hash of a file as a lowercase hex string

func (*Object) Metadata added in v1.59.1

func (o *Object) Metadata(ctx context.Context) (metadata fs.Metadata, err error)

Metadata returns metadata for an object

It should return nil if there is no Metadata

func (*Object) ModTime

func (o *Object) ModTime(ctx context.Context) time.Time

ModTime returns the modification time of the object

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

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 a boolean showing if 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) (err error)

Update the object from in with modTime and size

type Options
