Functions

func DiscardReader

func DiscardReader(src io.Reader)

DiscardReader anything from the reader

func MustReadReader

func MustReadReader(r io.Reader) []byte

MustReadReader read contents from io.Reader, will panic on error

func NewIOReader

func NewIOReader(in any) io.Reader

NewIOReader instance by input: string, bytes, io.Reader

func NewScanner

func NewScanner(in any) *bufio.Scanner

NewScanner instance by input data or reader

func QuietFprint

func QuietFprint(w io.Writer, ss ...string)

QuietFprint to writer, will ignore error

func QuietFprintf

func QuietFprintf(w io.Writer, tpl string, vs ...any)

QuietFprintf to writer, will ignore error

func QuietFprintln

func QuietFprintln(w io.Writer, ss ...string)

QuietFprintln to writer, will ignore error

func QuietWriteString

func QuietWriteString(w io.Writer, ss ...string)

QuietWriteString to writer, will ignore error

func ReadString

func ReadString(r io.Reader) string

ReadString read contents from io.Reader

Types

type WriteWrapper

type WriteWrapper struct {
	Out io.Writer
}

WriteWrapper warp io.Writer support more operate methods.

func NewWriteWrapper

func NewWriteWrapper(w io.Writer) *WriteWrapper

NewWriteWrapper instance

func (*WriteWrapper) String

func (w *WriteWrapper) String() string

String get write data string

func (*WriteWrapper) Write

func (w *WriteWrapper) Write(p []byte) (n int, err error)

Write bytes data

func (*WriteWrapper) WriteByte

func (w *WriteWrapper) WriteByte(c byte) error

WriteByte data

func (*WriteWrapper) WriteString

func (w *WriteWrapper) WriteString(s string) (n int, err error)

WriteString data

func (*WriteWrapper) Writef

func (w *WriteWrapper) Writef(tpl string, vs ...any) (n int, err error)

Writef data to output
