Method ParseSource

cel/env.go:680–686

ParseSource parses the input source to an Ast and/or set of Issues. Parsing has failed if the returned Issues value and its Issues.Err() value is non-nil. Issues should be inspected if they are non-nil, but may not represent a fatal error. It is possible to have both non-nil Ast and Issues values

(src Source)

// It is possible to have both non-nil Ast and Issues values returned from this call; however,
// the mere presence of an Ast does not imply that it is valid for use.
func (e *Env) ParseSource(src Source) (*Ast, *Issues) {
	parsed, errs := e.prsr.Parse(src)
	if len(errs.GetErrors()) > 0 {
		return nil, &Issues{errs: errs}
	}
	return &Ast{source: src, impl: parsed}, nil
}

// Program generates an evaluable instance of the Ast within the environment (Env).
func (e *Env) Program(ast *Ast, opts ...ProgramOption) (Program, error) {
