Enum hwlocality::object::distance::AddDistancesError

pub enum AddDistancesError {
    BadKind(FlagsError<DistancesKind>),
    BadObjectsCount(usize),
    ForeignEndpoint(ForeignObjectError),
    InconsistentData,
    NameContainsNul,
}

Available on crate feature hwloc-2_5_0 only.

Failed to add a new distance matrix to the topology

Variants

BadKind(FlagsError<DistancesKind>)

Available on crate feature hwloc-2_1_0 only.

Provided kind is invalid

Either it contains DistancesKind::HETEROGENEOUS_TYPES, which should not be set by you (it will be automatically set by hwloc through scanning of the provided object list), or it contains several of the “FROM_” and “MEANS_” kinds, which are mutually exclusive.

BadObjectsCount(usize)

Provided callback returned too many or too few objects

hwloc only supports distances matrices involving 2 to c_uint::MAX objects.

ForeignEndpoint(ForeignObjectError)

Provided callback returned one or more enpoint objects that do not belong to this Topology

InconsistentData

Provided callback returned incompatible objects and distances arrays

If we denote N the length of the objects array, the distances array should contain N.pow(2) elements.

NameContainsNul

Provided name contains NUL chars

Trait Implementations

impl Clone for AddDistancesError

fn clone(&self) -> AddDistancesError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddDistancesError

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

Formats the value using the given formatter.

impl Display for AddDistancesError

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

Formats the value using the given formatter.

impl Error for AddDistancesError

fn source(&self) -> Option<&(dyn Error + 'static)>

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 AddDistancesError

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

Converts to this type from the input type.

impl From<DistancesKind> for AddDistancesError

fn from(value: DistancesKind) -> Self

Converts to this type from the input type.

impl From<ForeignObjectError> for AddDistancesError

fn from(source: ForeignObjectError) -> Self

Converts to this type from the input type.

impl From<NulError> for AddDistancesError

fn from(_: NulError) -> Self

Converts to this type from the input type.

impl From<ParameterError<DistancesKind>> for AddDistancesError

impl Hash for AddDistancesError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl PartialEq for AddDistancesError

fn eq(&self, other: &AddDistancesError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
