# Concorrência e async / await { #concurrency-and-async-await }

Detalhes sobre a sintaxe `async def` para *funções de operação de rota* e alguns conceitos de código assíncrono, concorrência e paralelismo.

Se você estiver utilizando bibliotecas de terceiros que dizem para você chamar as funções com `await`, como:

```Python

		{"000000000000bogus", 0, "invalid byte in chunk length"},
		{"00000000000000000", 0, "http chunk length too large"}, // could accept if we wanted
		{"10000000000000000", 0, "http chunk length too large"},
		{"00000000000000001", 0, "http chunk length too large"}, // could accept if we wanted
	}
	for i := uint64(0); i <= 1234; i++ {
		tests = append(tests, testCase{in: fmt.Sprintf("%x", i), want: i})
	}
	for _, tt := range tests {

				var zb0006 uint32
				zb0006, err = dc.ReadArrayHeader()
				if err != nil {
					err = msgp.WrapError(err, zb0001, "Bins")
					return
				}
				if zb0006 != uint32(24) {
					err = msgp.ArrayError{Wanted: uint32(24), Got: zb0006}
					return
				}
				for zb0003 := range zb0002.Bins {
					err = zb0002.Bins[zb0003].DecodeMsg(dc)
					if err != nil {
						err = msgp.WrapError(err, zb0001, "Bins", zb0003)
						return

        for (int t = 0; t < threadCount; t++) {
            final int threadId = t;
            executor.submit(() -> {
                try {
                    startLatch.await(); // Wait for all threads to be ready

                    for (int i = 0; i < opsPerThread; i++) {
                        String share = "share" + (threadId % 3); // Use 3 different shares

* `seek(offset)`: Va a la posición de bytes `offset` (`int`) en el archivo.
    * Por ejemplo, `await myfile.seek(0)` iría al inicio del archivo.
    * Esto es especialmente útil si ejecutas `await myfile.read()` una vez y luego necesitas leer el contenido nuevamente.
* `close()`: Cierra el archivo.

Como todos estos métodos son métodos `async`, necesitas "await" para ellos.
