Struct BackgroundTaskManager 

pub struct BackgroundTaskManager { /* private fields */ }

Implementations

impl BackgroundTaskManager

pub fn new() -> Self

Create an empty BackgroundTaskManager with no running tasks.

pub async fn spawn(&mut self, id: String, cmd: &str) -> Result<()>

Spawn a shell command as a background task with the given ID. stdout is piped for AEGIS_PROGRESS parsing.

pub fn status(&self, id: &str) -> &'static str

Returns “running” if the task exists, “not_found” otherwise.

pub async fn cancel(&mut self, id: &str)

Cancel a task by sending kill signal (tokio sends SIGKILL). Note: tokio’s Child::kill() sends SIGKILL on Unix. For graceful shutdown, callers should use a 5-second timeout then call this method. A future improvement would use nix::sys::signal to send SIGTERM first.

pub async fn wait_all(&mut self, ids: &[&str]) -> Vec<Option<ExitStatus>>

Wait for all specified tasks to complete.

pub async fn wait_any(&mut self, ids: &[&str]) -> Option<(String, ExitStatus)>

Wait for any one of the specified tasks to complete. Returns the ID and exit status of the first task that finishes. (6.2.4)

Trait Implementations

impl Default for BackgroundTaskManager

fn default() -> Self

Returns the “default value” for a type.

impl Drop for BackgroundTaskManager

fn drop(&mut self)

Executes the destructor for this type.

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.
