}

Errors owned by the ArceOS runtime layer.

Variants

Irq(IrqError)

Interrupt discovery or registration failed.

Allocation(AllocError)

Runtime-owned storage allocation failed.

Task(TaskError)

The scheduler rejected a runtime-owned task operation.

SerialConfig(ConfigError)

A UART rejected its requested configuration.

ConsoleHandoff(ConsoleHandoffError)

A platform console ownership transition was requested out of order.

SerialConsoleBusy

Another serial runtime already owns console log routing.

ConsoleFailedClosed

The runtime console handoff failed after early ownership was revoked.

SerialNotStarted

A serial operation requires a running port.

SerialControlBusy

The bounded serial control queue is full.

WouldBlock

A bounded runtime queue has no capacity without waiting.

OperationNotSupported

The selected runtime capability does not support the operation.

InvalidCpu

A CPU index is outside the runtime’s online CPU set.

Fields

cpu: usize

Trait Implementations

impl Clone for RuntimeError

fn clone(&self) -> RuntimeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RuntimeError

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

impl Eq for RuntimeError

impl Error for RuntimeError

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.
