Safe Rust bindings to WinFSP with examples.

Warning

A best effort has been made to keep Rust's aliasing rules in mind, and provide a safe and sound wrapper over WinFSP. However, FFI with WinFSP involves a lot of pointers that end up as references and the nature of FFI makes it difficult to test with miri. While ntptfs is used to test the correctness of the bindings, there is still a chance these bindings are unsound.

Please file a bug report if you encounter unsoundness when using the safe APIs of these bindings.

Usage

By default, winfsp-rs builds against an included import library. To build against the installed WinFSP libraries, enable the system feature. The path will automatically be determined via the Registry.

[dependencies.winfsp]
version = "0.11"
features = ["system"]

Delay-loading

To enable delay-loading of WinFSP, add winfsp to build-dependencies and call winfsp::build::winfsp_link_delayload() in the build script. This is required for winfsp-rs.

Cargo.toml

[build-dependencies]
winfsp = "0.11"

build.rs

fn main() { 
    winfsp::build::winfsp_link_delayload();
}

Debugging

Debug output can be enabled with the debug feature. Debug output will be written to standard output, and redirection of output is not configurable at this time.

[dependencies.winfsp]
features = ["debug"]

Building on Stable Rust

It is recommended you build winfsp-rs on nightly Rust as it relies on io_error_more and strict_provenance. However, it is possible to build winfsp-rs on stable Rust without support for these features.

[dependencies.winfsp]
default-features = false
features = ["stable"]

Using with windows-sys

With default features, the winfsp crate includes helper utilities and From implementations for error types in the version of the windows crate at the time of publishing. If you wish to use winfsp without windows types, disable the windows-rs crate feature.

[dependencies.winfsp]
default-features = false
features = ["stable", "nightly"]

Testing

ntptfs-winfsp-rs, a port of ntptfs to winfsp-rs is used to test the bindings. It passes all tests that ntptfs passes at the same elevation level.
