Struct StderrObserver 

pub struct StderrObserver { /* private fields */ }

The default CommandObserver: writes one line per command to stderr (never stdout, so a stdout JSON-RPC transport stays clean), prefixed with a short tag. Format: `<tag>: <program> <args…> (cwd: <dir>) -> <status> in <dur>`.

Implementations

impl StderrObserver

pub fn new(tag: impl Into<Arc<str>>) -> Self

A stderr observer tagged tag (a short prefix that identifies the source, e.g. the server binary name).

Trait Implementations

impl Clone for StderrObserver

fn clone(&self) -> StderrObserver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandObserver for StderrObserver

fn on_command(&self, record: &CommandRecord<'_>)

Called once per observed command, synchronously, after it finishes (or, for a streaming ProcessRunner::start, right after the handle is returned). Keep it cheap and non-blocking; it runs on the calling task.

impl Debug for StderrObserver

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

Formats the value using the given formatter.

impl Default for StderrObserver

fn default() -> Self

Tagged command.
