Functions ¶
Types ¶
type Directory ¶
Directory describes a union Directory
This is a wrapped object contains all candidates
func (*Directory) ModTime ¶
ModTime returns the modification date of the directory It returns the latest ModTime of all candidates
func (*Directory) SetMetadata ¶
SetMetadata sets metadata for an DirEntry
It should return fs.ErrorNotImplemented if it can't set metadata
func (*Directory) SetModTime ¶
SetModTime sets the metadata on the DirEntry to set the modification date
If there is any other metadata it does not overwrite it.
type Errors ¶
type Errors []error
The Errors type wraps a slice of errors
func (Errors) Err ¶
Err returns an error interface that filtered nil, or nil if no non-nil Error is presented.
type Fs ¶
type Fs struct {
// contains filtered or unexported fields
}
Fs represents a union of upstreams
func (*Fs) ChangeNotify ¶
func (f *Fs) ChangeNotify(ctx context.Context, fn func(string, fs.EntryType), ch <-chan time.Duration)
ChangeNotify calls the passed function with a path that has had changes. If the implementation uses polling, it should adhere to the given interval. At least one value will be written to the channel, specifying the initial value and updated values might follow. A 0 Duration should pause the polling. The ChangeNotify implementation must empty the channel regularly. When the channel gets closed, the implementation should stop polling and release resources.
func (*Fs) CleanUp ¶
CleanUp the trash in the Fs
Implement this if you have a way of emptying the trash or otherwise cleaning up old versions of files.
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) DirCacheFlush ¶
func (f *Fs) DirCacheFlush()
DirCacheFlush resets the directory cache - used in testing as an optional interface
func (*Fs) DirMove ¶
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) DirSetModTime ¶
DirSetModTime sets the directory modtime for dir
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) MkdirMetadata ¶
func (f *Fs) MkdirMetadata(ctx context.Context, dir string, metadata fs.Metadata) (fs.Directory, error)
MkdirMetadata makes the root directory of the Fs object
func (*Fs) Move ¶
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) Purge ¶
Purge all files in the directory
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
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) 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
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
type Object ¶
Object describes a union Object
This is a wrapped object which returns the Union Fs as its parent
func (*Object) Open ¶
func (o *Object) Open(ctx context.Context, options ...fs.OpenOption) (io.ReadCloser, error)
Open opens the file for read. Call Close() on the returned io.ReadCloser
func (*Object) SetModTime ¶
SetModTime sets the metadata on the object to set the modification date
func (*Object) SetTier ¶
SetTier performs changing storage tier of the Object if multiple storage classes supported
func (*Object) UnWrapUpstream ¶
UnWrapUpstream returns the upstream Object that this Object is wrapping
func (*Object) Update ¶
func (o *Object) Update(ctx context.Context, in io.Reader, src fs.ObjectInfo, options ...fs.OpenOption) error
Update in to the object 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), Upload should either return an error or update the object properly (rather than e.g. calling panic).
