ErrDurationMustBeString is returned when a non-string value is presented to be deserialized as a ConfigDuration
var ErrDurationMustBeString = errors.New("cannot JSON unmarshal something other than a string into a ConfigDuration")
Duration is just an alias for time.Duration that allows serialization to YAML as well as JSON.
type Duration struct {
time.Duration `validate:"required"`
}
func (d Duration) MarshalJSON() ([]byte, error)
MarshalJSON returns the string form of the duration, as a byte array.
func (d *Duration) UnmarshalJSON(b []byte) error
UnmarshalJSON parses a string into a ConfigDuration using time.ParseDuration. If the input does not unmarshal as a string, then UnmarshalJSON returns ErrDurationMustBeString.
func (d *Duration) UnmarshalYAML(unmarshal func(interface{}) error) error
UnmarshalYAML uses the same format as JSON, but is called by the YAML parser (vs. the JSON parser).
