Enum TopologyError 

pub enum TopologyError {
    InvalidCpuList(String),
    NotPowerOfTwo(usize),
    EmptySet,
    Io(Error),
    CpuNotAllowed(usize),
}

What can go wrong discovering topology or resolving a PartitionConfig.

Variants

InvalidCpuList(String)

A cpulist string was not the "0-7,16-23" form.

Tuple Fields

0: String

The offending list, trimmed.

NotPowerOfTwo(usize)

A partition count was not a power of two.

Tuple Fields

0: usize

The rejected count.

EmptySet

A CPU set was empty where a partition needs at least one CPU.

Io(Error)

A syscall or sysfs read failed, or a pool could not be built.

Tuple Fields

0: Error

The underlying error.

CpuNotAllowed(usize)

An explicit set named a CPU outside the process’s affinity mask.

Tuple Fields

0: usize

The CPU index that is outside the process’s affinity mask.

Trait Implementations

impl Debug for TopologyError

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

Formats the value using the given formatter.

impl Display for TopologyError

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

Formats the value using the given formatter.

impl Error for TopologyError

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 TopologyError

fn from(err: Error) -> Self

Converts to this type from the input type.
