Implementations

impl Machine

pub async fn assert_service_active(&self, unit: &str) -> Result<()>

pub async fn assert_service_inactive(&self, unit: &str) -> Result<()>

pub async fn assert_curl(&self, url: &str, expected_status: u16) -> Result<()>

pub async fn assert_journal_clean(&self, unit: &str) -> Result<()>

pub async fn assert_file_exists(&self, path: &str) -> Result<()>

pub async fn assert_file_not_exists(&self, path: &str) -> Result<()>

pub async fn wait_for_service( &self, unit: &str, timeout: Duration, ) -> Result<()>

impl Machine

pub async fn spawn( image: &Image, test_id: &str, ssh_port: u16, opts: &SpawnOpts, ) -> Result<Self>

pub async fn exec(&self, cmd: &str) -> Result<ExecOutput>

Run a command inside the VM via SSH.

pub async fn exec_streaming( &self, cmd: &str, prefix: &str, ) -> Result<ExecOutput>

Run a command inside the VM via SSH, streaming stdout/stderr to the terminal. Returns the exit status (Ok if success, Err if non-zero).

pub async fn wait_for_exit(&mut self, timeout: Duration)

Wait for the qemu process to exit on its own (e.g., after a clean sudo poweroff). Returns once the process is gone or timeout elapses. Used before snapshotting so the disk is fully released.

pub async fn destroy(self) -> Result<()>

Shut down the VM and clean up files.

pub fn keep_alive(self)

Print SSH connection info for debugging, then detach. VM keeps running until the user kills it or the process exits.

Trait Implementations

impl Drop for Machine

fn drop(&mut self)

Kill the QEMU process if it’s still alive. Needed because tokio’s Child::drop does NOT reap the process by default, so any early return from spawn_* (e.g. SSH timeout during wait_for_ssh) would otherwise orphan a QEMU holding the forwarded SSH port. Async destroy paths that want to survive this (keep_alive) use std::mem::forget to skip Drop entirely.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
