Types ¶
type BadFieldType ¶
BadFieldType is the error which indicates that a type of a field of the option store is neither a boolean, a number, a string, nor an array of numbers or strings.
func (BadFieldType) Error ¶
func (e BadFieldType) Error() string

Example ¶
package main import ( "fmt" "reflect" "github.com/sttk/cliargs/errors" ) func main() { e := errors.BadFieldType{ Option: "foo-bar", Field: "FooBar", Type: reflect.TypeOf(int(0)), } fmt.Printf("%s\n", e.Error()) }
