## Examples
```python
#Basic add example
def add(x, y): return x + y

if __name__ == '__main__':
    rets = [add(x, y) for x in range(0, 5) for y in range(5, 10)]
```

```python
#Example bulk add using aiovast class
from aiovast import Vast

def add(x, y): return x + y

if __name__ == '__main__':
    aiovast = Vast()
    args = [[[x, y]] for x in range(0, 5) for y in range(5, 10)]
    rets = aiovast.run_in_eventloop(add, args)
```

```python
#Example using Vast context manager
from aiovast import Vast

def add(x, y): return x + y

if __name__ == '__main__':
    args = [[[x, y]] for x in range(0, 5) for y in range(5, 10)]
    with Vast() as aiovast:
        rets = aiovast.run_in_eventloop(add, args)
```

```python
#Example bulk add using decorator
from aiovast.decorators import vast_loop

@aiovast_loop(max_async_pool=16)
def add_in_bulk(x, y):
    return x+y

if __name__ == '__main__':
    args = [[[x, y]] for x in range(0, 5) for y in range(5, 10)]
    rets = add_in_bulk(args)
```

```python
#Vast session for sending bulk requests
from aiovast.requests import VastSession

session = VastSession(max_async_pool=4)
calls = [
    (['get', 'https://www.google.com'], {'headers': {'User-Agent':'custom'}}),
    (['post', 'https://www.github.com'], )
]
responses = session.bulk_requests(calls)
```
