Struct hwlocality::object::search::MissingObjCpuSetError

pub struct MissingObjCpuSetError(/* private fields */);

Error returned when a search algorithm that requires a cpuset is applied to an object that doesn’t have one.

The presence of a cpuset greatly simplifies some search algorithms as it allows asserting that an object is a child of another with simple bitmap operations, rather than requiring topology tree traversal. Therefore, relatively complex search operations may only be applied to objects with a cpuset (i.e. normal and memory objects) and will fail with this error if applied to other object types.

Trait Implementations

impl Clone for MissingObjCpuSetError

fn clone(&self) -> MissingObjCpuSetError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MissingObjCpuSetError

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

Formats the value using the given formatter.

impl Default for MissingObjCpuSetError

fn default() -> MissingObjCpuSetError

Returns the “default value” for a type.

impl Display for MissingObjCpuSetError

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

Formats the value using the given formatter.

impl Error for MissingObjCpuSetError

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<'topology> From<&'topology TopologyObject> for MissingObjCpuSetError

fn from(object: &'topology TopologyObject) -> Self

Converts to this type from the input type.

impl From<MissingObjCpuSetError> for ClosestObjectsError

fn from(source: MissingObjCpuSetError) -> Self

Converts to this type from the input type.

impl PartialEq for MissingObjCpuSetError

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