Usage

Import

type Taxable struct {
	Index       int
	Description string `csv:"Item"`
	Cost        float32
	Tax         float32
	Total       float32
}

Read

Parses each line into a item of given slice

func main() {
	response, _ := http.Get("https://people.sc.fsu.edu/~jburkardt/data/csv/taxables.csv")
	// define a slice with a type
	var taxables []Taxable
	// initiate the reader
	r := csv.NewReader(response.Body)
	// read all lines into the referenced slice 
	err := r.ReadAll(&taxables)

	if err != nil {
		fmt.Println(err)
	}

	fmt.Println(taxables)
}
