Method CreateAST

tools/compiler/compiler.go:472–482

CreateAST creates a CEL AST from a checked expression file. The file must be in one of the following formats: - Binarypb - Textproto

(_ Compiler)

// - Binarypb
// - Textproto
func (c *CompiledExpression) CreateAST(_ Compiler) (*cel.Ast, map[string]any, error) {

		return nil, nil, fmt.Errorf("invalid file extension wanted: .binarypb or .textproto found: %v", format)
	}
	if err := loadProtoFile(c.Path, format, &expr); err != nil {
		return nil, nil, err
	}
	return cel.CheckedExprToAst(&expr), nil, nil
