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 added in v1.6.1 

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, connectionStringConfig configmap.Simple) (config *configmap.Map)

ConfigMap creates a configmap.Map from the *RegInfo and the configName passed in. If connectionStringConfig has any entries (it may be nil), then it will be added to the lookup with the highest priority.

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

func ConfigString added in v1.50.20 

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, e.g. ("myremote", "ignore-size") into an environment name "RCLONE_CONFIG_MYREMOTE_IGNORE_SIZE"

func CopyConfig added in v1.55.0 

func CopyConfig(dstCtx, srcCtx context.Context) context.Context

CopyConfig copies the global config (if any) from srcCtx into dstCtx returning the new context.

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 added in v1.50.20 

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 (e.g. Onedrive, Box) don't support range requests which index from the end.

func GetModifyWindow 

func GetModifyWindow(ctx context.Context, 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)

MimeTypeFromName returns a guess at the mime type from the name

func NewUsageValue 

func NewUsageValue(value int64) *int64

func OpenOptionHeaders 

func OpenOptionHeaders(options []OpenOption) (headers map[string]string)

OpenOptionHeaders adds each header found in options to the headers map provided the key was non empty.

It returns a nil map if options was empty

func OptionToEnv 

func OptionToEnv(name string) string

OptionToEnv converts an option name, e.g. "ignore-size" into an environment name "RCLONE_IGNORE_SIZE"

func ParseDuration 

func ParseDuration(age string) (time.Duration, error)

ParseDuration parses a duration string. Accept ms|s|m|h|d|w|M|y suffixes. Defaults to second if not provided

func Register

Fs modules should use this in an init() function

func UnmarshalJSONFlag added in v1.55.0 

func UnmarshalJSONFlag(in []byte, x interface{ Set(string) error }, setInt func(int64) error) error

type RangeOption 

type RangeOption struct {
	Start int64
	End   int64
}

RangeOption defines an HTTP Range option with start and end. If either start or end are < 0 then they will be omitted.

End may be bigger than the Size of the object in which case it will be capped to the size of the object.

Note that the End is inclusive, so to fetch 100 bytes you would use RangeOption{Start: 0, End: 99}

If Start is specified but End is not then it will fetch from Start to the end of the file.

If End is specified, but Start is not then it will fetch the last End bytes.

Examples: 

RangeOption{Start: 0, End: 99} - fetch the first 100 bytes
RangeOption{Start: 100, End: 199} - fetch the second 100 bytes
RangeOption{Start: 100, End: -1} - fetch bytes from offset 100 to the end
RangeOption{Start: -1, End: 100} - fetch the last 100 bytes
