Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BadPerfSample

NoPerfData

DebugFsNotMounted

ThreadPollingError

NumberParserError

SelfTrace

UnsupportedProgramType

ProgramNotLoaded

InvalidElf

InvalidProgramLength

InvalidInstructionLength

KernelVersionNotFound

MissingRelocationSection(u32)

InvalidMapObject

LinuxError(String, Errno)

If Errno is EPERM when receiving this error, check that the calling process has appropriate capabilities (CAP_SYS_ADMIN, CAP_NET_ADMIN, and CAP_BPF are typically required) and that the user’s memlock limit is high enough to load your programs. If the memlock limit is too low, this library exposes a set_memlock_limit(new_limit) function which can raise it for you.

PerfEventDoesNotExist

PerfIoctlError(Error)

CStringConversionError(NulError)

MapNotLoaded

ProgramNotFound(String)

MapNotFound(String)

NoProgramVersionLoaded(Vec<OxidebpfError>)

FileIOError

Utf8StringConversionError

CpuOnlineFormatError

BadPageSize

BadPageCount

UnsupportedEventType

MultipleErrors(Vec<OxidebpfError>)

UncaughtMountNsError

BpfProgLoadError((Box<OxidebpfError>, String))

MapValueSizeMismatch

MapKeySizeMismatch

ProgramGroupAlreadyLoaded

RetryError(String)

LockError

KretprobeNamingError

This error is returned when trying to attach a kretprobe with debugfs. There’s a chance we need to change the path name and retry, which is what this error indicates.
