hermit-rs-template

An application template for Hermit for Rust.

Requirements

rustup
QEMU or Uhyve for running the application

Transform your application into a Hermit image:

(this is already done in this repo)

Add the hermit dependency for hermit targets in Cargo.toml.
```
cargo add --target 'cfg(target_os = "hermit")' hermit
```

Make sure we link against hermit in main.rs:

#[cfg(target_os = "hermit")]
use hermit as _;

Usage

Install the Rust Standard Library for Hermit

See rust-std-hermit.

Note that rust-std-hermit is not available for the stable toolchain channel but for specific channels of stable Rust versions. See rust-toolchain.toml.

Build the Hermit Application

$ cargo build --target x86_64-unknown-hermit

Run the Application in Uhyve

$ uhyve target/x86_64-unknown-hermit/debug/hermit-rs-template

For more details, see uhyve's README.

Run the Application in QEMU

Download the loader binary from its releases page.
