BoolToBoolValueFunc is a mapstructure hook that looks for an incoming bool mapped to a BoolValue and does the translation.

Float64ToUintValueFunc is a mapstructure hook that looks for an incoming float64 mapped to a UintValue and does the translation.

StringToDurationValueFunc is a mapstructure hook that looks for an incoming string mapped to a DurationValue and does the translation.

StringToStringValueFunc is a mapstructure hook that looks for an incoming string mapped to a StringValue and does the translation.

Visit will call the visitor function on the path if it's a file, or for each file in the path if it's a directory.

ConfigDecodeHook should be passed to mapstructure in order to decode into the *Value objects here.

BoolValue provides a flag value that's aware if it has been set.

DurationValue provides a flag value that's aware if it has been set.

StringValue provides a flag value that's aware if it has been set.

UintValue provides a flag value that's aware if it has been set.

AppendSliceValue implements the flag.Value interface and allows multiple calls to the same variable to append a list.

FlagMapValue is a flag implementation used to provide key=value semantics multiple times.

VisitFn is a callback that gets a chance to visit each file found during a traversal with visit().
