Error when building a ProcessorTopology.

Variants

NoVps

Failed to configure at least one VP.

TooManyVps

Too many virtual processors.

Fields

requested: u32

The number of processors requested.

max: u32

The maximum number of processors.

ApicIdLimitExceeded(u32)

Not all processors will be addressable in XAPIC mode.

InvalidVpIndices

VpInfo indices must be linear and start at 0

StdIoError(Error)

Failed to query the topology information from Device Tree.

Trait Implementations

impl Debug for InvalidTopology

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

Formats the value using the given formatter.

impl Display for InvalidTopology

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

Formats the value using the given formatter.

impl Error for InvalidTopology

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.
