Expand description

Filesystem-specific errors

Variants§

NotFound

File or directory not found

AlreadyExists

Path already exists

PermissionDenied

Permission denied

NotADirectory

Target is not a directory

NotAFile

Target is not a file

IsADirectory

Target is a directory (when file expected)

ReadOnly

Filesystem is read-only

InvalidPath

Invalid path format

NoRootFs

Root filesystem not mounted

AlreadyMounted

Path already has a mount point

NotMounted

Path is not a mount point

UnknownFsType

Unknown filesystem type

IoError

I/O error during operation

DirectoryNotEmpty

Directory is not empty

TooManyOpenFiles

File descriptor table is full

BadFileDescriptor

Invalid file descriptor

NotSupported

Operation not supported on this node type

NotASymlink

Target is not a symbolic link

FileTooLarge

File size exceeds maximum supported limit

CorruptedData

On-disk data is corrupt or has invalid magic number

SymlinkLoop

Too many levels of symbolic links (ELOOP)

NoSpace

No space left on device (ENOSPC)

Trait Implementations§

impl Clone for FsError

fn clone(&self) -> FsError

Returns a duplicate of the value. Read more

1.0.0§

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

Performs copy-assignment from source. Read more

impl Debug for FsError

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

Formats the value using the given formatter. Read more

impl From<FsError> for KernelError

fn from(err: 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 ==.

1.0.0§

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

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