MP table construction error.

Variants

NoProcessors

At least one processor must be described.

InvalidApicId

APIC IDs must be contiguous and start at zero.

Fields

index: usize

Processor index.

apic_id: u32

Supplied APIC ID.

expected: u32

Required APIC ID.

ApicIdTooLarge

MP 1.4 processor entries contain only an 8-bit APIC ID.

Fields

index: usize

Processor index.

apic_id: u32

Supplied APIC ID.

TooManyEntries

The entry count or table length cannot be represented.

NoIoApicId

The I/O APIC ID register exposes only four ID bits.

Fields

processor_count: usize

Number of processor APIC IDs already in use.

InvalidIrq(u32)

ISA IRQs are limited to 0 through 15.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl Eq for Error
