Functions

func EqualFoldWithoutChars

func EqualFoldWithoutChars(s1, s2 string) bool

EqualFoldWithoutChars checks string <s1> and <s2> equal case-insensitively, with/without chars '-'/'_'/'.'/' '.

func IsArray

func IsArray(value interface{}) bool

IsArray checks whether given value is array/slice. Note that it uses reflect internally implementing this feature.

func IsLetter

func IsLetter(b byte) bool

IsLetter checks whether the given byte b is a letter.

func IsLetterLower

func IsLetterLower(b byte) bool

IsLetterLower checks whether the given byte b is in lower case.

func IsLetterUpper

func IsLetterUpper(b byte) bool

IsLetterUpper checks whether the given byte b is in upper case.

func IsNumeric

func IsNumeric(s string) bool

IsNumeric checks whether the given string s is numeric. Note that float string like "123.456" is also numeric.

func NewReadCloser

func NewReadCloser(content []byte, repeatable bool) io.ReadCloser

NewRepeatReadCloser creates and returns a RepeatReadCloser object.

func NewReadCloserWithReadCloser

func NewReadCloserWithReadCloser(r io.ReadCloser, repeatable bool) (io.ReadCloser, error)

NewRepeatReadCloserWithReadCloser creates and returns a RepeatReadCloser object with given io.ReadCloser.

func RemoveSymbols

func RemoveSymbols(s string) string

RemoveSymbols removes all symbols from string and lefts only numbers and letters.

func ReplaceByMap

func ReplaceByMap(origin string, replaces map[string]string) string

ReplaceByMap returns a copy of <origin>, which is replaced by a map in unordered way, case-sensitively.

func UcFirst

func UcFirst(s string) string

UcFirst returns a copy of the string s with the first letter mapped to its upper case.

Types

type ReadCloser

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

ReadCloser implements the io.ReadCloser interface which is used for reading request body content multiple times.

Note that it cannot be closed.

func (*ReadCloser) Close

func (b *ReadCloser) Close() error

Close implements the io.ReadCloser interface.

func (*ReadCloser) Read

func (b *ReadCloser) Read(p []byte) (n int, err error)

Read implements the io.ReadCloser interface.
