Functions

func NewFs

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

NewFs constructs an Fs from the path, bucket:path

Types

type Fs

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

Fs represents a remote qingstor server

func (*Fs) Copy

func (f *Fs) 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 (*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(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(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 that doing a directory traversal.

func (*Fs) Mkdir

func (f *Fs) Mkdir(dir string) error

Mkdir creates the bucket 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(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) Put

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

Put created a new object

func (*Fs) Rmdir

func (f *Fs) Rmdir(dir string) error

Rmdir delete a bucket

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 qingstor object

func (*Object) Fs

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

Fs returns read only access to the Fs that this object is part of

func (*Object) Hash

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

Hash returns the selected checksum of the file If no checksum is available it returns ""

func (*Object) MimeType

func (o *Object) MimeType() string

MimeType of an Object if known, "" otherwise

func (*Object) ModTime

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

ModTime returns the modification date of the file It should return a best guess if one isn't available

func (*Object) Open

func (o *Object) Open(options ...fs.OpenOption) (io.ReadCloser, error)

Open opens the file for read. Call Close() on the returned io.ReadCloser

func (*Object) Remote

func (o *Object) Remote() string

Remote returns the remote path

func (*Object) Remove

func (o *Object) Remove() error

Remove this object

func (*Object) SetModTime

func (o *Object) SetModTime(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 the file

func (*Object) Storable

func (o *Object) Storable() bool

Storable says whether this object can be stored

func (*Object) String

func (o *Object) String() string

String returns a description of the Object

func (*Object) Update

func (o *Object) Update(in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) error

Update in to the object

type Options

type Options struct {
	EnvAuth           bool          `config:"env_auth"`
	AccessKeyID       string        `config:"access_key_id"`
	SecretAccessKey   string        `config:"secret_access_key"`
	Endpoint          string        `config:"endpoint"`
	Zone              string        `config:"zone"`
	ConnectionRetries int           `config:"connection_retries"`
	UploadCutoff      fs.SizeSuffix `config:"upload_cutoff"`
	ChunkSize         fs.SizeSuffix `config:"chunk_size"`
	UploadConcurrency int           `config:"upload_concurrency"`
}

Options defines the configuration for this backend
