qemu-fw-cfg-rs

A Rust library for reading [fw_cfg] from QEMU.

Usage

Add the following to your Cargo.toml:

toml [dependencies] qemu-fw-cfg = "0.1"

To use qemu-fw-cfg without alloc, you can use this instead:

toml [dependencies] qemu-fw-cfg = { version = "0.1", default-features = false }

Examples

```rust use qemufwcfg::FwCfg;

// Verify that we are inside QEMU. if runninginqemu() { // Create a new FwCfg instance. let fwcfg = unsafe { FwCfg::new().unwrap() }; // Retrieve information of a file. let file = fwcfg.findfile("etc/igd-opregion").unwrap(); // Read data from the file. let data = fwcfg.read_file(&file); } ```

Rust support

The minimum supported Rust version for qemu-fw-cfg is 1.59.0.

However, testing for x86 currently requires Rust Nightly as it uses Cargo’s build-std.
