Functions

func HasSideEffects

func HasSideEffects(info *types.Info, e ast.Expr) bool

HasSideEffects reports whether evaluation of e has side effects.

func LineStart

func LineStart(f *token.File, line int) token.Pos

LineStart returns the position of the start of the specified line within file f, or NoPos if there is no line of that number.
