cross-fs

This project provides cross-platform extensions for std::fs::File, avoiding the hassle of conditional compilation when writing code for different operating systems. We also provide support for Direct I/O.

Features

• Direct I/O: Implements Direct I/O on supported platforms. You can create aligned buffers using cross-fs::avec!(n).
• Positioned I/O: Defines a unified interface through the PositionedExt trait.
• Vectored I/O: Defined through the VectoredExt trait, with implementation for Windows code when Direct I/O is enabled (since Vectored I/O is only available on Windows when Direct I/O is enabled, the standard library doesn't implement it by default, and this project fills that gap).

Supported Operating Systems

Since I develop on WSL, I can only design code for Linux and Windows. If you're willing to help add support for other platforms, PRs are very welcome!

Feature Flags

• align-512: Changes memory alignment size to 512 (default is 4096). In most cases, you shouldn't need to enable this feature.

Contributing

Suggestions for improvements or Pull Requests are welcome. If you think the crate should add new features or if there are any bugs that need fixing, please let me know through an issue, and I'll do my best to fix and implement them.
