Functions ¶
Types ¶
type Fs ¶
type Fs struct {
// contains filtered or unexported fields
}
Fs represents a combine of upstreams
func (*Fs) ChangeNotify ¶
func (f *Fs) ChangeNotify(ctx context.Context, notifyFunc 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) 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) 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) 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 wrapped Object
This is a wrapped Object which knows its path prefix
func (*Object) Metadata ¶
Metadata returns metadata for an object
It should return nil if there is no Metadata
type Options ¶
type Options struct {
Upstreams fs.SpaceSepList `config:"upstreams"`
}
Options defines the configuration for this backend
