Functions

func CheckClose 

func CheckClose(c io.Closer, err *error)

CheckClose is a utility function used to check the return from Close in a defer statement.

func CompareDirEntries 

func CompareDirEntries(a, b DirEntry) int

CompareDirEntries returns 1 if a > b, 0 if a == b and -1 if a < b If two dir entries have the same name, compare their types (directories are before objects)

func ConfigMap 

func ConfigMap(fsInfo *RegInfo, configName string) (config *configmap.Map)

ConfigMap creates a configmap.Map from the *RegInfo and the configName passed in.

If fsInfo is nil then the returned configmap.Map should only be used for reading non backend specific parameters, such as "type".

func ConfigString 

func ConfigString(f Fs) string

ConfigString returns a canonical version of the config string used to configure the Fs as passed to fs.NewFs

func ConfigToEnv 

func ConfigToEnv(section, name string) string

ConfigToEnv converts a config section and name, eg ("myremote", "ignore-size") into an environment name "RCLONE_CONFIG_MYREMOTE_IGNORE_SIZE"

func Debugf 

func Debugf(o interface{}, text string, args ...interface{})

Debugf writes debugging output for this Object or Fs. Use this for debug only. The user must have to specify -vv to see this.

func DirEntryType 

func DirEntryType(d DirEntry) string

DirEntryType returns a string description of the DirEntry, either "object", "directory" or "unknown type XXX"

func Errorf 

func Errorf(o interface{}, text string, args ...interface{})

Errorf writes error log output for this Object or Fs. It should always be seen by the user.

func FileExists 

func FileExists(ctx context.Context, fs Fs, remote string) (bool, error)

FileExists returns true if a file remote exists. If remote is a directory, FileExists returns false.

func Fingerprint 

func Fingerprint(ctx context.Context, o ObjectInfo, fast bool) string

Fingerprint produces a unique-ish string for an object.

This is for detecting whether an object has changed since we last saw it, not for checking object identity between two different remotes - operations.Equal should be used for that.

If fast is set then Fingerprint will only include attributes where usually another operation is not required to fetch them. For example if fast is set then this won't include hashes on the local backend.

func FixRangeOption 

func FixRangeOption(options []OpenOption, size int64)

FixRangeOption looks through the slice of options and adjusts any RangeOption~s found that request a fetch from the end into an absolute fetch using the size passed in and makes sure the range does not exceed filesize. Some remotes (eg Onedrive, Box) don't support range requests which index from the end.

func GetModifyWindow 

func GetModifyWindow(fss ...Info) time.Duration

GetModifyWindow calculates the maximum modify window between the given Fses and the Config.ModifyWindow parameter.

func Infof 

func Infof(o interface{}, text string, args ...interface{})

Infof writes info on transfers for this Object or Fs. Use this level for logging transfers, deletions and things which should appear with the -v flag.

func LogDirName 

func LogDirName(f Fs, dir string) interface{}

LogDirName returns an object for the logger, logging a root directory which would normally be "" as the Fs

func LogLevelPrintf 

func LogLevelPrintf(level LogLevel, o interface{}, text string, args ...interface{})

LogLevelPrintf writes logs at the given level

func LogPrintf 

func LogPrintf(level LogLevel, o interface{}, text string, args ...interface{})

LogPrintf produces a log string from the arguments passed in

func Logf 

func Logf(o interface{}, text string, args ...interface{})

Logf writes log output for this Object or Fs. This should be considered to be Info level logging. It is the default level. By default rclone should not log very much so only use this for important things the user should see. The user can filter these out with the -q flag.

func MimeType 

func MimeType(ctx context.Context, o ObjectInfo) (mimeType string)

MimeType returns the MimeType from the object, either by calling the MimeTyper interface or using MimeTypeFromName

func MimeTypeDirEntry 

func MimeTypeDirEntry(ctx context.Context, item DirEntry) string

MimeTypeDirEntry returns the MimeType of a DirEntry

It returns "inode/directory" for directories, or uses MimeType(Object)

func ConfigFs(path string) (fsInfo *RegInfo, configName, fsPath string, config *configmap.Map, err error)

ConfigFs makes the config for calling NewFs with.

It parses the path which is of the form remote:path

Remotes are looked up in the config file. If the remote isn't found then NotFoundInConfigFile will be returned.

func Find 

func Find(name string) (*RegInfo, error)

Find looks for a RegInfo object for the name passed in. The name can be either the Name or the Prefix.

Services are looked up in the config file

func MustFind 

func MustFind(name string) *RegInfo

MustFind looks for an Info object for the type name passed in

Services are looked up in the config file

Exits with a fatal error if not found

func ParseRemote 

func ParseRemote(path string) (fsInfo *RegInfo, configName, fsPath string, err error)

ParseRemote deconstructs a path into configName, fsPath, looking up the fsName in the config file (returning NotFoundInConfigFile if not found)

func (*RegInfo) FileName 

func (ri *RegInfo) FileName() string

FileName returns the on disk file name for this backend

type SeekOption 

type SeekOption struct {
	Offset int64
}

func (*SeekOption) String 

func (o *SeekOption) String() string

String formats the option into human readable form

type SetTierer 

type SetTierer interface {
	// SetTier performs changing storage tier of the Object if
	// multiple storage classes supported
	SetTier(tier string) error
}

SetTierer is an optional interface for Object

type SizeSuffix 

type SizeSuffix int64

const (
	Byte SizeSuffix = 1 << (iota * 10)
	KibiByte
	MebiByte
	GibiByte
	TebiByte
	PebiByte
	ExbiByte
)

Common multipliers for SizeSuffix

func (*SizeSuffix) Scan

type SizeSuffixList 

type SizeSuffixList []SizeSuffix

SizeSuffixList is a slice SizeSuffix values

func (SizeSuffixList) Len 

func (l SizeSuffixList) Len() int

func (SizeSuffixList) Less 

func (l SizeSuffixList) Less(i, j int) bool

func (SizeSuffixList) Sort 

func (l SizeSuffixList) Sort()

func (SizeSuffixList) Swap 

func (l SizeSuffixList) Swap(i, j int)

type SpaceSepList 

type SpaceSepList []string

SpaceSepList is a space separated config value It uses the encoding/csv rules for quoting and escaping

Example 
for _, s := range []string{
	`remotea:test/dir remoteb:`,
	`"remotea:test/space dir" remoteb:`,
	`"remotea:test/quote""dir" remoteb:`,
} {
	var l SpaceSepList
	must(l.Set(s))
	fmt.Printf("%#v\n", l)
}

Output:

fs.SpaceSepList{"remotea:test/dir", "remoteb:"}
fs.SpaceSepList{"remotea:test/space dir", "remoteb:"}
fs.SpaceSepList{"remotea:test/quote\"dir", "remoteb:"}

func (*SpaceSepList) Scan 

func (l *SpaceSepList) Scan(s fmt.ScanState, ch rune) error

type UnWrapper 

type UnWrapper interface {
	// UnWrap returns the Fs that this Fs is wrapping
	UnWrap() Fs
}

UnWrapper is an optional interfaces for Fs

type Usage 

type Usage struct {
	Total   *int64 `json:"total,omitempty"`   // quota of bytes that can be used
	Used    *int64 `json:"used,omitempty"`    // bytes in use
	Trashed *int64 `json:"trashed,omitempty"` // bytes in trash
	Other   *int64 `json:"other,omitempty"`   // other usage eg gmail in drive
	Free    *int64 `json:"free,omitempty"`    // bytes which can be uploaded before reaching the quota
	Objects *int64 `json:"objects,omitempty"` // objects in the storage system
}

Usage is returned by the About call

If a value is nil then it isn't supported by that backend
