Struct netemul::guest::Controller

pub struct Controller { /* private fields */ }

A controller for managing a single virtualized guest.

Controller instantiates a guest on creation and exposes methods for communicating with the guest. The guest lifetime is tied to the controller’s; dropping the controller will shutdown the guest.

Implementations

impl Controller

pub async fn new( name: impl Into<String>, network: &TestNetwork<'_>, mac: Option<MacAddress> ) -> Result<Controller, Error>

Instantiates a guest and installs it on the provided network. If mac is provided, the guest will be given the mac address; otherwise one will be picked by virtio. Returns an error if the sandbox already contains a guest.

pub async fn put_file( &self, local_path: &str, remote_path: &str ) -> Result<(), Error>

Copies the file located at local_path within the namespace of the executing process to remote_path on the guest.

pub async fn get_file( &self, local_path: &str, remote_path: &str ) -> Result<(), Error>

Copies the file located at remote_path on the guest to local_path within the namespace of the current process.

pub async fn exec_with_output_logged( &self, command: &str, env: Vec<EnvironmentVariable>, input: Option<&str> ) -> Result<(), Error>

Executes command on the guest with environment variables held in env, writing input into the remote process’s stdin and logs the remote process’s stdout and stderr.

Returns an error if the executed command’s exit code is non-zero.

pub async fn exec( &self, command: &str, env: Vec<EnvironmentVariable>, input: Option<&str> ) -> Result<(i32, String, String), Error>

Executes command on the guest with environment variables held in env, writing input into the remote process’s stdin and returning the remote process’s (stdout, stderr).
