Struct insertWrapAssign

cmd/errtrace/main.go:1144–1147

insertWrapAssign wraps a variable in-place with an errtrace.Wrap call. This is used for naked returns in functions with named return values For example, it will turn this: func foo() (err error) { // ... return } Into this: func foo() (err error) { // ... err = errtrace.Wrap(err); ret

//		err = errtrace.Wrap(err); return
//	}
type insertWrapAssign struct {
	Names  []string  // names of variables to wrap
	Before token.Pos // position to insert before
}

func (e *insertWrapAssign) Pos() token.Pos {
	return e.Before
