Error type for external users

Variants

BaseNotDirectory

The fd given as a base was not a directory so the operation was not possible

NotAFile

Expected a file but found not a file

InvalidFd

The fd given was not usable

AlreadyExists

File exists

Lock

The filesystem has failed to lock a resource.

IOError

Something failed when doing IO. These errors can generally not be handled. It may work if tried again.

AddressInUse

The address was in use

AddressNotAvailable

The address could not be found

BrokenPipe

A pipe was closed

ConnectionAborted

The connection was aborted

ConnectionRefused

The connection request was refused

ConnectionReset

The connection was reset

Interrupted

The operation was interrupted before it could finish

InvalidData

Invalid internal data, if the argument data is invalid, use InvalidInput

InvalidInput

The provided data is invalid

NotConnected

Could not perform the operation because there was not an open connection

EntryNotFound

The requested file or directory could not be found

NoDevice

The requested device couldn’t be accessed

PermissionDenied

Caller was not allowed to perform this operation

TimedOut

The operation did not complete within the given amount of time

UnexpectedEof

Found EOF when EOF was not expected

WouldBlock

Operation would block, this error lets the caller know that they can try again

WriteZero

A call to write returned 0

DirectoryNotEmpty

Directory not Empty

StorageFull

UnknownError

Some other unhandled error. If you see this, it’s probably a bug.

Unsupported

Operation is not supported on this filesystem

Trait Implementations

impl Clone for FsError

fn clone(&self) -> FsError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FsError

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

Formats the value using the given formatter.

impl Display for FsError

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

Formats the value using the given formatter.

impl Error for FsError

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<Error> for FsError

fn from(io_error: Error) -> FsError

Converts to this type from the input type.

impl From<FsError> for WasiStateCreationError

fn from(source: FsError) -> Self

Converts to this type from the input type.

impl PartialEq for FsError

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for FsError

impl Eq for FsError

impl StructuralPartialEq for FsError
