Enum KernelError 

pub enum KernelError {
    UnknownEnvironment(String),
    InvalidState {
        action: &'static str,
        state: KernelPhase,
    },
    DuplicateBundle(&'static str),

}

Failure during kernel registration, compile, boot, or shutdown.

Variants

UnknownEnvironment(String)

Environment::from_name received an empty name.

InvalidState

An operation was invoked in a phase that does not allow it.

Fields

action: &'static str

Attempted operation (register, compile, boot, or shutdown).

state: KernelPhase

Current lifecycle phase.

DuplicateBundle(&'static str)

Two bundles were registered with the same BundleInterface::name.

UnknownBundleDependency

A bundle listed a dependency that was never registered.

Fields

bundle: &'static str

Bundle that declared the dependency.

dependency: &'static str

Missing dependency name.

CyclicBundleDependency(&'static str)

Bundle dependencies form a cycle; 0 is one member of the cycle.

Bundle

A bundle returned an error from build, boot, or shutdown.

Fields

bundle: &'static str

Bundle name.

phase: &'static str

Lifecycle method that failed.

message: String

Underlying error text.

Trait Implementations

impl Clone for KernelError

fn clone(&self) -> KernelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Eq for KernelError

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.

impl PartialEq for KernelError

fn eq(&self, other: &KernelError) -> 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.
