Functions

func AppendError 

func AppendError(base error, err error) error

Appends on error to another, allowing for operations that return multiple errors to remain compatible within a single-valued context.

func ConvertToString(in interface{}) (string, error)

func ConvertToTime 

func ConvertToTime(in interface{}) (time.Time, error)

func DetectTimeFormat 

func DetectTimeFormat(in string) string

func GenericMarshalJSON 

func GenericMarshalJSON(in interface{}, extraData ...map[string]interface{}) ([]byte, error)

func IsBoolean 

func IsBoolean(inI interface{}) bool

func IsBooleanFalse 

func IsBooleanFalse(inI interface{}) bool

func IsBooleanTrue 

func IsBooleanTrue(inI interface{}) bool

func IsFloat 

func IsFloat(in interface{}) bool

func IsHexadecimal added in v1.7.49 

func IsHexadecimal(in interface{}) bool

func IsInteger 

func IsInteger(in interface{}) bool

func IsKind 

func IsKind(in interface{}, kinds ...reflect.Kind) bool

Dectect whether the concrete underlying value of the given input is one or more Kinds of value.

func IsNumeric 

func IsNumeric(in interface{}) bool

func IsTime 

func IsTime(inI interface{}) bool

func IsZero 

func IsZero(value interface{}) bool

Returns whether the given value represents the underlying type's zero value

func JSONPath added in v1.9.3 

func JSONPath(data interface{}, query string, autowrap bool) (interface{}, error)

Performs a JSONPath query against the given object and returns the results. JSONPath description, syntax, and examples are available at http://goessner.net/articles/JsonPath/.

func ParseDuration 

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

func RegisterTypeHandler added in v1.5.55 

func RegisterTypeHandler(handler TypeConvertFunc, types ...string)

Register's a handler used for converting one type to another. Type are checked in the following manner: The input value's reflect.Type String() value is matched, falling back to its reflect.Kind String() value, finally checking for a special "*" value that matches any type. If the handler function returns nil, its value replaces the input value. If the special error type PassthroughType is returned, the original value is returned unmodified.

func ResolveValue 

func ResolveValue(in interface{}) interface{}

func SliceEach 

func SliceEach(slice interface{}, iterFn IterationFunc, preserve ...reflect.Kind) error

Iterate through each element of the given array, slice or channel; calling iterFn exactly once for each element. Otherwise, call iterFn one time with the given input as the argument.

func Sliceify added in v1.8.92 

func Sliceify(in interface{}) []interface{}

Takes some input value and returns it as a slice.

func ToString 

func ToString(in interface{}) (string, error)

Types

type ConvertType 

type ConvertType int
const (
	Invalid ConvertType = iota
	Bytes
	String
	Float
	Integer
	Time
	Boolean
	Nil
	UserDefined
)

func Detect added in v1.7.49 

func Detect(in interface{}) (ConvertType, interface{})

type IterationFunc 

type IterationFunc func(i int, value interface{}) error

type TimedReadCloser added in v1.8.30 

type TimedReadCloser struct {
	// contains filtered or unexported fields
}

A TimedReadCloser wraps an io.ReadCloser, keeping track of how long actually reading from and closing the ReadCloser took, as well as how many bytes were read.

Measurement starts from the first call to Read(), and ends when Close() is called.

func NewTimedReadCloser added in v1.8.30 

func NewTimedReadCloser(rc io.ReadCloser) *TimedReadCloser

func (*TimedReadCloser) BytesRead added in v1.8.30 

func (self *TimedReadCloser) BytesRead() int64

func (*TimedReadCloser) Close added in v1.8.30 

func (self *TimedReadCloser) Close() (err error)

func (*TimedReadCloser) CloseDuration added in v1.8.30 

func (self *TimedReadCloser) CloseDuration() time.Duration

func (*TimedReadCloser) Duration added in v1.8.30 

func (self *TimedReadCloser) Duration() time.Duration

func (*TimedReadCloser) LastReadAt added in v1.8.30 

func (self *TimedReadCloser) LastReadAt() time.Time

Return the time of the last call to Read()

func (*TimedReadCloser) Read added in v1.8.30 

func (self *TimedReadCloser) Read(b []byte) (int, error)

func (*TimedReadCloser) ReadDuration added in v1.8.30 

func (self *TimedReadCloser) ReadDuration() time.Duration

Return a running duration of how long reading has been happening. Updated on every call to Read().

func (*TimedReadCloser) Reset added in v1.8.30 

func (self *TimedReadCloser) Reset()

Reset the internal counters to zero. Useful after calling SetReadCloser().

func (*TimedReadCloser) SetReadCloser added in v1.8.30 

func (self *TimedReadCloser) SetReadCloser(rc io.ReadCloser)

Set the underlying io.ReadCloser. Does not call Reset(), so multiple ReadClosers can be cumulitively tracked.

func (*TimedReadCloser) SinceLastRead added in v1.8.30 

func (self *TimedReadCloser) SinceLastRead() time.Duration

Return the duration of time since the last Read() occurred.

func (*TimedReadCloser) StartedAt added in v1.8.30 

func (self *TimedReadCloser) StartedAt() time.Time

Return the time of the first call to Read().

type TypeConvertFunc added in v1.5.55 

type TypeConvertFunc func(in interface{}) (interface{}, error)
