Enum KernelError 

pub enum KernelError {
    Module(String),
    Bus(String),
    Registry(Error),
    ConfigNotFound(String),
    DuplicateModule(String),
    UnknownModule(String),
    Serde(Error),
    Denied {
        publisher: String,
        capability: String,
    },
    Other(Error),
}

All errors that can be produced by the kernel and its subsystems.

Variants

Module(String)

A module operation failed (load, start, stop, unload, etc.).

Bus(String)

A message could not be routed on the bus, e.g. because no receiver is listening or the channel was closed.

Registry(Error)

The state registry returned a database-level error.

ConfigNotFound(String)

A configuration key was not found in the registry.

DuplicateModule(String)

A duplicate module id was registered with the ModuleManager.

UnknownModule(String)

A module id was referenced that is not known to the manager.

Serde(Error)

JSON (de)serialization failed.

Denied

A publish was rejected because the publisher lacks the required capability.

Fields

publisher: String

The publisher that attempted the operation.

capability: String

The capability required.

Other(Error)

An unexpected, unclassified error.

Trait Implementations

impl Debug for KernelError

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

Formats the value using the given formatter.

impl Display for KernelError

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

Formats the value using the given formatter.

impl Error for KernelError

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.
