Errors produced by Linux inode, handle, and read-only FUSE mechanics.

Variants

ZeroInode

Inode zero is reserved by the FUSE protocol.

ZeroGeneration

Generation zero is rejected so stale inode records cannot silently bypass fencing.

RootInodeMismatch

The root record did not use inode one.

ScopeMismatch

A supplied record did not belong to the active root scope.

DuplicateInode

Two persisted records attempted to reuse one inode.

Fields

inode: u64

Conflicting inode number.

DuplicateItem

Two persisted records attempted to map one stable key to different inode records.

MissingInodeRecord

A backend item did not have a restored inode mapping.

UnknownInode

An inode was not known to the active mount session.

Fields

inode: u64

Unknown inode number.

StaleHandle

An open file or directory handle no longer belongs to the requested inode.

AccessModeMismatch

A file-handle operation did not match the access mode selected at open time.

HandleExhausted

In-memory handle allocation exhausted the native handle domain.

InvalidConfiguration

A mount or attribute policy used an invalid value.

Fields

reason: &'static str

Stable validation reason.

InvalidName

A file name cannot be represented by this string-based backend contract.

Fields

reason: &'static str

Stable validation reason.

NotDirectory

An operation required a directory but received a file.

NotFile

An operation required a regular file but received a directory.

InvalidBackendResponse

A product backend returned metadata that violated its scoped item contract.

Fields

reason: &'static str

Stable validation reason.

Backend(CloudBackendError)

The product-owned backend reported a classified failure.

WritebackStore(CloudFilesStoreError)

The product-owned durable writeback store reported a classified failure.

NamespaceStore(LinuxNamespaceMutationStoreError)

The product-owned durable namespace store reported a classified failure.

NamespaceMutationNotConfigured

Native create was requested without a product namespace transaction port.

Implementations

impl LinuxCloudFilesError

pub const fn error_code(&self) -> LinuxErrorCode

Returns the portable errno classification expected by the FUSE adapter.

Trait Implementations

impl Debug for LinuxCloudFilesError

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

Formats the value using the given formatter.

impl Display for LinuxCloudFilesError

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

Formats the value using the given formatter.

impl Error for LinuxCloudFilesError

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.
