The error 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.

AlreadyExists = 2

An entity already exists, often a file.

BadAddress = 3

Bad address.

BadState = 4

Bad internal state.

ConnectionRefused = 5

The connection was refused by the remote server,

ConnectionReset = 6

The connection was reset by the remote server.

DirectoryNotEmpty = 7

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

InvalidData = 8

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.

InvalidInput = 9

Invalid parameter/argument.

Io = 10

Input/output error.

IsADirectory = 11

The filesystem object is, unexpectedly, a directory.

NoMemory = 12

Not enough space/cannot allocate memory.

NotADirectory = 13

A filesystem object is, unexpectedly, not a directory.

NotConnected = 14

The network operation failed because it was not connected yet.

NotFound = 15

The requested entity is not found.

PermissionDenied = 16

The operation lacked the necessary privileges to complete.

ResourceBusy = 17

Device or resource is busy.

StorageFull = 18

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

UnexpectedEof = 19

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

Unsupported = 20

This operation is unsupported or unimplemented.

WouldBlock = 21

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

WriteZero = 22

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

Implementations

impl AxError

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 AxError

fn clone(&self) -> AxError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AxError

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

Formats the value using the given formatter.

impl Display for AxError

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

Formats the value using the given formatter.

impl PartialEq for AxError

fn eq(&self, other: &AxError) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for AxError

type Error = i32

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<AxError, <AxError as TryFrom<i32>>::Error>

Performs the conversion.

impl Copy for AxError

impl Eq for AxError

impl StructuralPartialEq for AxError
