Если вы используете сторонние библиотеки, которые нужно вызывать с `await`, например:

```Python
results = await some_library()

   */
  final transient int segmentShift;

  /** The segments, each of which is a specialized hash table. */
  final transient Segment<K, V, E, S>[] segments;

  /** The concurrency level. */
  final int concurrencyLevel;

  /** Strategy for comparing keys. */
  final Equivalence<Object> keyEquivalence;

  /** Strategy for handling entries and segments in a type-safe and efficient manner. */

}

var listCache sync.Map // map[string]listImports, keyed by contextName

// listSem is a semaphore restricting concurrent invocations of 'go list'. 'go
// list' has its own internal concurrency, so we use a hard-coded constant (to
// allow the I/O-intensive phases of 'go list' to overlap) instead of scaling
// all the way up to GOMAXPROCS.
var listSem = make(chan semToken, 2)

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

```Python

    /**
     * Deletes a document from the specified index with optimistic concurrency control.
     *
     * @param index       the index name
     * @param id          the document ID
     * @param seqNo       the sequence number for optimistic concurrency control
     * @param primaryTerm the primary term for optimistic concurrency control
     * @return true if the document was deleted successfully, false otherwise
