Errors that can occur when using the RAPL source.

Variants

RaplNotAvailable(String)

Intel RAPL interface is not available on this system.

NoDomains

No RAPL domains were discovered on this system.

RaplReadError(String)

Failed to read a value from a RAPL domain.

InvalidRaplPath(String)

A RAPL sysfs path could not be parsed or resolved.

InvalidSocketSpec(String)

The socket specification string is malformed.

SocketNotFound(u32)

The requested socket index does not exist in the discovered RAPL domains.

CommandNotFound(String)

A required system command was not found.

UnsupportedOS(String)

RAPL is only supported on Linux.

InsufficientPermissions

The process lacks the required permissions to access RAPL counters.

UnknownDomain(String)

A RAPL domain name could not be matched to a known type.

FailToOpenDomainCounter(String)

No CPU in the socket was able to open the perf counter for this domain. It can also appear if perf_event_open returns an error other than unsupported event for a specific CPU.

InvalidEventFormat(String)

The event format string for this domain could not be parsed.

DomainNotSupported(RaplDomainType)

This RAPL domain is not supported by the hardware.

PerfParanoid(PerfParanoidError)

The perf_event_paranoid level is too restrictive.

RetrieveScaleError

The energy scale factor could not be retrieved from the perf event.

IoError(Error)

Generic I/O error not covered by other variants.

ParseEnergyError(ParseIntError)

Failed to parse an energy value as an integer.

ParseDomainScale(ParseFloatError)

Failed to parse a domain scale value as a float.

NotEnoughSamples

Not enough snapshots have been taken to compute an energy delta.

MutexPoisoned

Trait Implementations

impl Debug for RaplError

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

Formats the value using the given formatter.

impl Display for RaplError

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

Formats the value using the given formatter.

impl Error for RaplError

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.
