The error kind type used by ArceOS.

Similar to std::io::ErrorKind.

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.

AddrInUse = 1

A socket address could not be bound because the address is already in use elsewhere.

AlreadyConnected = 2

The socket is already connected.

AlreadyExists = 3

An entity already exists, often a file.

ArgumentListTooLong = 4

Program argument list too long.

BadAddress = 5

Bad address.

BadFileDescriptor = 6

Bad file descriptor.

BadState = 7

Bad internal state.

BrokenPipe = 8

Broken pipe

ConnectionRefused = 9

The connection was refused by the remote server.

ConnectionReset = 10

The connection was reset by the remote server.

CrossesDevices = 11

Cross-device or cross-filesystem (hard) link or rename.

DirectoryNotEmpty = 12

A non-empty directory was specified where an empty directory was expected.

FilesystemLoop = 13

Loop in the filesystem or IO subsystem; often, too many levels of symbolic links.

IllegalBytes = 14

Illegal byte sequence.

InProgress = 15

The operation was partially successful and needs to be checked later on due to not blocking.

Interrupted = 16

This operation was interrupted.

InvalidData = 17

Data not valid for the operation were encountered.

Unlike InvalidInput, this typically means that the operation parameters were valid, however the error was caused by malformed input data.

For example, a function that reads a file into a string will error with InvalidData if the file’s contents are not valid UTF-8.

InvalidExecutable = 18

Invalid executable format.

InvalidInput = 19

Invalid parameter/argument.

Io = 20

Input/output error.

IsADirectory = 21

The filesystem object is, unexpectedly, a directory.

NameTooLong = 22

Filename is too long.

NoMemory = 23

Not enough space/cannot allocate memory.

NoSuchDevice = 24

No such device.

NoSuchProcess = 25

No such process.

NotADirectory = 26

A filesystem object is, unexpectedly, not a directory.

NotASocket = 27

The specified entity is not a socket.

NotATty = 28

Not a typewriter.

NotConnected = 29

The network operation failed because it was not connected yet.

NotFound = 30

The requested entity is not found.

OperationNotPermitted = 31

Operation not permitted.

OperationNotSupported = 32

Operation not supported.

OutOfRange = 33

Result out of range.

PermissionDenied = 34

The operation lacked the necessary privileges to complete.

ReadOnlyFilesystem = 35

The filesystem or storage medium is read-only, but a write operation was attempted.

ResourceBusy = 36

Device or resource is busy.

StorageFull = 37

The underlying storage (typically, a filesystem) is full.

TimedOut = 38

The I/O operation’s timeout expired, causing it to be canceled.

TooManyOpenFiles = 39

The process has too many files open.

UnexpectedEof = 40

An error returned when an operation could not be completed because an “end of file” was reached prematurely.

Unsupported = 41

This operation is unsupported or unimplemented.

WouldBlock = 42

The operation needs to block to complete, but the blocking operation was requested to not occur.

WriteZero = 43

An error returned when an operation could not be completed because a call to write() returned Ok(0).

Implementations

impl AxErrorKind

pub fn as_str(&self) -> &'static str

Returns the error description.

pub const fn code(self) -> i32

Returns the error code value in i32.

Trait Implementations

impl Clone for AxErrorKind

fn clone(&self) -> AxErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AxErrorKind

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

Formats the value using the given formatter.

impl Display for AxErrorKind

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

Formats the value using the given formatter.

impl EnumCount for AxErrorKind

const COUNT: usize = 43usize

impl Hash for AxErrorKind

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AxErrorKind

fn cmp(&self, other: &AxErrorKind) -> Ordering

This method returns an Ordering between self and other.

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

Tests greater than (for self and other) and is used by the > operator.
