Enum SupervisorError 

pub enum SupervisorError {
    Unavailable(String),
    Io(String),
    Refused(String),
}

Errors an adapter can return.

Typed (rather than Box<dyn Error>) so the dispatcher can choose different copy for each class without string-matching on message bodies.

Variants

Unavailable(String)

Adapter is not configured for this invocation (no daemon binary installed, or --no-headless flag set).

Io(String)

Transport-level failure — socket gone, permission denied, pipe closed mid-call.

Refused(String)

The daemon refused the request (e.g. asked to stop while already stopping). Rendered as a warn line, not an alert — the call was understood, just not honored.

Trait Implementations

impl Clone for SupervisorError

fn clone(&self) -> SupervisorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SupervisorError

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

Formats the value using the given formatter.

impl Display for SupervisorError

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

Formats the value using the given formatter.

impl Error for SupervisorError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for SupervisorError

fn eq(&self, other: &SupervisorError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
