Functions ¶
Types ¶
type Fs ¶
type Fs struct {
// contains filtered or unexported fields
}
Fs represents a remote b2 server
func (*Fs) Copy ¶
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) List ¶
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 ¶
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) NewObject ¶
NewObject finds the Object at remote. If it can't be found it returns the error fs.ErrorObjectNotFound.
func (*Fs) PublicLink ¶
func (f *Fs) PublicLink(ctx context.Context, remote string, expire fs.Duration, unlink bool) (link string, err error)
PublicLink returns a link for downloading without account
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 bucket
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
type Object ¶
type Object struct {
// contains filtered or unexported fields
}
Object describes a b2 object
func (*Object) ModTime ¶
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
SHA-1 will also be updated once the request has completed.
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) SetModTime ¶
SetModTime sets the modification time of the Object
type Options ¶
type Options struct {
Account string `config:"account"`
Key string `config:"key"`
Endpoint string `config:"endpoint"`
TestMode string `config:"test_mode"`
Versions bool `config:"versions"`
VersionAt fs.Time `config:"version_at"`
HardDelete bool `config:"hard_delete"`
UploadCutoff fs.SizeSuffix `config:"upload_cutoff"`
CopyCutoff fs.SizeSuffix `config:"copy_cutoff"`
ChunkSize fs.SizeSuffix `config:"chunk_size"`
DisableCheckSum bool `config:"disable_checksum"`
DownloadURL string `config:"download_url"`
DownloadAuthorizationDuration fs.Duration `config:"download_auth_duration"`
MemoryPoolFlushTime fs.Duration `config:"memory_pool_flush_time"`
MemoryPoolUseMmap bool `config:"memory_pool_use_mmap"`
Enc encoder.MultiEncoder `config:"encoding"`
}
Options defines the configuration for this backend
