Asynchronous file operations.

AIOFile Real asynchronous file operations with asyncio support. Status Development - Stable Features Since version 2.0.0 using caio, which contains linux libaio and two thread-based implementations (c-based and pure-python). AIOFile has no internal pointer. You should pass offset and chunk_size for each operation or use helpers (Reader or Writer). The simplest way is to use async_open for creating object with file-like interface. For Linux using implementation based on libaio. For POSIX (MacOS X and optional Linux) using implementation based on threadpool. Otherwise using pure-python thread-based implementation. Implementation chooses automatically depending on system compatibility. Limitations Linux native AIO implementation is not able to open special files. Asynchronous operations against special fs like /proc/ /sys/ are not supported by the kernel. It's not a aiofile's or caio issue. In these cases, you might switch to thread-based implementations (see Troubleshooting sect
