Project Description
# asyncwrap

asyncwrap helps wrapping synchronous calls into asynchronous ones, and it based
on asyncio and threading modules.

For example, sqlalchemy is synchronous and not built to be compatible with
asyncio. asyncwrap offers simple wrappers which if used in right places can make
code run concurrent and be faster. For more information please check examples
directory.

asyncwrap is library/framework agnostic and can be used with any Python >=3.5
code.

All you need can be found by importing single class called Async:
```python
from asyncwrap import Async
```

Async class has following methods:
```python
Async.set_default_loop
Async.With
Async.For
Async.Call
Async.ExecutorCall
Async.ThreadCall
```


# Example

```python
import time
import random
import asyncio
import tempfile
import functools

from asyncwrap import Async


async def do_async_with(loop):
async with Async.With(tempfile.TemporaryFile()) as f:
await Async.Call(f.write, b'hello world')
await asyncio.sleep(random.random())
await Async.Call(f.seek, 0)
await asyncio.sleep(random.random())
data = await Async.Call(f.read)
print('do_async_with', data)


async def do_async_for(loop, s, e):
async for i in Async.For(range(s, e)):
await asyncio.sleep(random.random())
print('do_async_for', i)


async def do_async_call(loop, f, t):
r = await Async.Call(f, t)
print('do_async_call', f, t, r)
return r


async def do_async_executor_call(loop, f, t):
r = await Async.ExecutorCall(f, t)
print('do_async_executor_call', f, t, r)
return r


async def do_async_thread_call(loop, f, t):
r = await Async.ThreadCall(f, t)
print('do_async_thread_call', f, t, r)
return r


def blocking_sleep(t):
time.sleep(t)
return t


if __name__ == '__main__':
loop = asyncio.get_event_loop()
Async.set_default_loop(loop)

tasks = [
# with
asyncio.ensure_future(do_async_with(loop)),
asyncio.ensure_future(do_async_with(loop)),

# for
asyncio.ensure_future(do_async_for(loop, 0, 10)),
asyncio.ensure_future(do_async_for(loop, 20, 30)),

# call
asyncio.ensure_future(
do_async_call(loop, blocking_sleep, random.random() * 5)),

asyncio.ensure_future(
do_async_call(loop, blocking_sleep, random.random() * 5)),

# executor call
asyncio.ensure_future(
do_async_executor_call(loop, blocking_sleep, 5)),

asyncio.ensure_future(
do_async_executor_call(loop, blocking_sleep, 5)),

# thread call
asyncio.ensure_future(
do_async_thread_call(loop, blocking_sleep, 5)),

asyncio.ensure_future(
do_async_thread_call(loop, blocking_sleep, 4)),

asyncio.ensure_future(
do_async_thread_call(loop, blocking_sleep, 3)),

asyncio.ensure_future(
do_async_thread_call(loop, blocking_sleep, 2)),
]

loop.run_until_complete(asyncio.wait(tasks))
loop.close()
```
