Struct ProcessRegistry 

pub struct ProcessRegistry { /* private fields */ }

Registry of active processes.

Tracks running commands by id. One-shot processes are removed when they complete; background processes remain until explicitly removed or cancelled.

Wired into the live app: background run_shell results are registered here, the :bg command lists them, and cancel_all runs on quit.

Implementations

impl ProcessRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register( &self, command: Vec<String>, cwd: PathBuf, kind: ProcessKind, cancel: CancelToken, ) -> u64

Register a new process and return its id.

pub fn get(&self, id: u64) -> Option<ActiveProcess>

Look up an active process by id.

pub fn cancel(&self, id: u64) -> bool

Request cancellation of a process by id.

Returns true if the process existed and cancellation was signalled.

pub fn remove(&self, id: u64) -> Option<ActiveProcess>

Remove a completed process from the registry.

pub fn cancel_all(&self)

Cancel all active processes.

pub fn background_ids(&self) -> impl Iterator<Item = u64>

Iterate over active background process ids.

pub fn announce(&self, id: u64) -> bool

Mark an application-visible background process as announced.

pub fn drain_completed(&self) -> Vec<ProcessResult>

Return completed background results after their start event was observed.

pub fn shutdown(&self) -> Vec<ProcessResult>

Cancel and reap every owned process, returning all final results.

Trait Implementations

impl Clone for ProcessRegistry

fn clone(&self) -> ProcessRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProcessRegistry

fn default() -> ProcessRegistry

Returns the “default value” for a type.

impl Drop for ProcessRegistry

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.
