vhaudiquet 185ffeeb3d fix(error): let the typed variants survive the anyhow conversion
KvmUnavailable and ArchNotAvailable were raised as anyhow context
strings and wrapped into Other at the public boundary, so the
matching lib.rs documents never fired. They now ride at the top of
an anyhow chain and the manual From recovers them by downcast;
KvmUnavailable carries the open(2) error as its source instead of
swallowing it.

This changes the API: KvmUnavailable is a struct variant.

$ ecrou run -it ubuntu
root@ecrou-vm-m2glhl:/# 

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))
}
