# Available Methods
- Downloader class Instance
   `Non-blocking , params = [fake_useragent:bool,chunk_size:int ,download_path:str] optinals`
   
        dl = Downloader()
-   Download [ `download(self,url)` ]  

        uuid = await dl.download(url)
- Errors [` iserror(self, uuid) `]
    ` : Returns -  Error Or None
    , Even On cancel It returns an error "{uuid} Cancelled"`

    ```
    await dl.iserror(uuid)
    ```


- cancel [ `cancel(self, uuid)` ]

       await dl.cancel(uuid)
- Get Status [ `status(self, uuid)` ]  
    
        response = await dl.status(uuid)
        


        returns a dict

        """
        filename:str
        file_type :str
        total_size :int
        total_size_str : str
        downloaded :int
        downloaded_str :str
        progress:int
        download_speed:str
        complete :bool
        download_path:str

        """

- is_active returns : bool [ `is_active( self,uuid )` ]` - on cancel ,error , download complete  return False`
    
        result = await dl.is_active(uuid)


## Usage
Example :
___

```py

from pyaiodl import Downloader, errors
import asyncio
url = "https://speed.hetzner.de/100MB.bin"


async def main():
    dl = Downloader()
    # you can pass your
    # custom chunk size and Download Path
    # dl = Downloader(download_path="/your_dir/", chunk_size=10000)
    uuid = await dl.download(url)
    try:
        while await dl.is_active(uuid):

            r = await dl.status(uuid)

               #cancel
            if r['progress'] > 0:
                try:
                    await dl.cancel("your_uuid")
                except errors.DownloadNotActive as na:
                    print(na)


            print(f"""
            Filename: {r['filename']}
            Total : {r['total_size_str']}
            Downloaded : {r['downloaded_str']}
            Download Speed : {r['download_speed']}
            progress: {r['progress']}
             """)

            # let him breath  for a second:P
            await asyncio.sleep(1)

    # If You are putting uuid  manually Than its better handle This Exception
    except errors.InvalidId:
        print("not valid uuid")
        return

    # when loop Breaks There are 2 Possibility
    # either Its An error Or Download Complete
    # Cancelled Is also count as error
    if await dl.iserror(uuid):
        print(await dl.iserror(uuid))

    else:
        # Final filename / path
       print("Download completed : ", r['download_path'])


asyncio.get_event_loop().run_until_complete(main())

```
