You can learn how to <a href="https://heyapi.dev/openapi-ts/get-started" class="external-link" target="_blank">install `@hey-api/openapi-ts`</a> and read about the <a href="https://heyapi.dev/openapi-ts/output" class="external-link" target="_blank">generated output</a> on their website.

### Using the SDK { #using-the-sdk }

Now you can import and use the client code. It could look like this, notice that you get autocompletion for the methods:

	input        chan *queueItem        // input for workers
	queue        chan *queueItem        // output from workers in order
	err          error                  // global error state, only touched by Reader.Read
	bufferPool   bpool.Pool[[]byte]     // pool of []byte objects for input
	csvDstPool   bpool.Pool[[][]string] // pool of [][]string used for output
	close        chan struct{}          // used for shutting down the splitter before end of stream

		var result string
		if parser.allowABI {
			result = obj.DconvWithABIDetail(&emptyProg, &addr)
		} else {
			result = obj.Dconv(&emptyProg, &addr)
		}
		if result != test.output {
			t.Errorf("fail at %s: got %s; expected %s\n", test.input, result, test.output)
		}
	}
}

	parser := newParser("amd64")
	testOperandParser(t, parser, amd64OperandTests)

        String result = response.toString();

        // Assert that the output string contains the expected field values
        assertNotNull(result);
        assertTrue(result.contains("SmbComOpenAndXResponse"));
        assertTrue(result.contains("fid=1"));
