Functions

func Decode

func Decode(r io.Reader, slice any) (err error)

*

• @description:
• @param {[]byte} data
• @param {any} v 数组地址
• @return {*}

func DecodeWithAnsi

func DecodeWithAnsi(r io.Reader, v any) (err error)

*

• @description: 解析ansi格式的csv
• @param {io.Reader} r
• @param {any} v 数组地址
• @return {*}

Types

type DecodeOpts

type DecodeOpts struct {
	Comma            rune // field delimiter (set to ',' by default)
	Comment          rune // comment character for start of line
	LazyQuotes       bool // allow lazy quotes
	TrimLeadingSpace bool // trim leading space
}

DecodeOpts specifies options to modify decoding behavior.

type Decoder

type Decoder interface {
	// DecodeNext populates v with the values from the next row in the
	// Decoder's Reader.
	//
	// On the first call to DecodeNext, the first row in the reader will be
	// used as the header row to map CSV fields to struct fields, and the
	// second row will be read to populate v.
	DecodeNext(v interface{}) error

	// Opts specifies options to modify decoding behavior.
	//
	// It returns the Decoder, to support chaining.
	Opts(DecodeOpts) Decoder
}

Decoder reads and decodes CSV rows from an input stream.

func NewDecoder

func NewDecoder(r io.Reader) Decoder

NewDecoder returns a Decoder that reads from r.

func NewDocedeWithAnsi

func NewDocedeWithAnsi(r io.Reader) Decoder

*

• @description: ansi 的编码识别
• @param {io.Reader} r
• @return {*}

type InvalidUnmarshalError

type InvalidUnmarshalError struct {
	Type reflect.Type
}

An InvalidUnmarshalError describes an invalid argument passed to Unmarshal. (The argument to Unmarshal must be a non-nil pointer.)

func (*InvalidUnmarshalError) Error

func (e *InvalidUnmarshalError) Error() string
