Embed ecrou into your project

ecrou is both a library and a tiny CLI frontend around it. The library is embeddable into any project, allowing to use microVMs easily.

Rust

ecrou is a Rust library, which can just be called:

use ecrou::vm::RunOptions;
use ecrou::NoProgress;

fn main() -> ecrou::Result<std::process::ExitCode> {
    let code = ecrou::vm::run(
        &RunOptions {
            image: "ubuntu:resolute".into(),
            command: vec!["uname".into(), "-a".into()],
            ..RunOptions::default()
        },
        &NoProgress,
    )?;
    Ok(std::process::ExitCode::from(code.clamp(0, 255) as u8))
}
