Variants

NoError = 0

BadAlignment = 1

BadAddress = 2

OutOfMemory = 3

MemoryInUse = 4

InterruptNotFound = 5

InterruptInUse = 6

InvalidString = 7

ServerExists = 8

ServerNotFound = 9

ProcessNotFound = 10

ProcessNotChild = 11

ProcessTerminated = 12

Timeout = 13

InternalError = 14

ServerQueueFull = 15

ThreadNotAvailable = 16

UnhandledSyscall = 17

InvalidSyscall = 18

ShareViolation = 19

InvalidThread = 20

InvalidPid = 21

UnknownError = 22

AccessDenied = 23

UseBeforeInit = 24

DoubleFree = 25

DebugInProgress = 26

InvalidLimit = 27

NotFound = 28

For lookups that result in not found (e.g., searching for keys, resources, names)

InvalidCoding = 29

Used when try_from/try_into can’t map a number into a smaller number of options

HardwareError = 30

Used for ECC errors, glitches, power failures, etc.

SerializationError = 31

Used when buffers & messages fail to serialize or deserialize

InvalidArgument = 32

Used when a call is correct but its arguments are out of bounds, invalid, or otherwise poorly specified

NetworkError = 33

Catch-all for networking related problems (unreachable network, etc.)

StorageError = 34

Catch-all for storage related problems (particularly write/read ECC errors)

Unavailable = 35

Catch-all for resources that are busy or already allocated

ParseError = 36

For failed parsing attempts

InvalidCore = 37

Invalid core number on multi-core APIs

VerificationError = 38

Reports when verification/check steps fail. Thrown when correctly functioning algorithms determine that an object is invalid.

SecurityError = 39

Used to report higher-severity system security/integrity issues, such as glitch attacks, ECC errors, memory violations, bad states for hardened bools. Note that bad passwords/credentials should use “AccessDenied”

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<i32> for Error

fn from(src: i32) -> Self

Converts to this type from the input type.

impl From<usize> for Error

fn from(src: usize) -> Self

Converts to this type from the input type.

impl Copy for Error
