}

A managed-worker lifecycle operation that could not be carried out.

Variants

NotCommissioned

No supervision policy is configured, so nothing may be started.

UnknownDeployment

The named deployment does not exist.

Fields

name: String

Deployment primary key the caller asked for.

Store

The durable deployment store refused or failed.

Fields

source: StoreError

Underlying store failure.

ExecutableUnresolved

This server’s own executable could not be identified.

Fields

detail: String

Operating-system failure text.

ExecutableUnreadable

The executable bytes could not be read for identity capture.

Fields

path: String

Path that could not be read.

detail: String

Operating-system failure text.

Process

The contained child could not be spawned or observed.

Fields

name: String

Deployment primary key.

source: ProcessGroupError

Underlying containment failure.

StopIncomplete

A stop was asked for and could not be PROVEN complete.

This exists so that “stopped” is never reported on the strength of bookkeeping: the only path to a Stopped status runs through a process group that a signal-zero probe found empty, and every other outcome arrives here instead.

Fields

name: String

Deployment primary key.

detail: String

What was observed instead of an empty process group.

TaskLost

A supervision task ended abnormally (panicked or was aborted).

Fields

name: String

Deployment primary key.

detail: String

Join failure text.

StatePoisoned

A supervisor lock was poisoned by a panicking holder.

Fields

detail: String

Poison report.

Implementations

impl SupervisionError

pub const fn remedy(&self) -> Option<&'static str>

The operator remedy carried by this failure, when it has one.

Trait Implementations

impl Debug for SupervisionError

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

Formats the value using the given formatter.

impl Display for SupervisionError

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

Formats the value using the given formatter.

impl Error for SupervisionError

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>)
