Common error type for all Ext4 operations.

Variants

NotAbsolute

An operation that requires an absolute path was attempted on a relative path.

NotASymlink

An operation that requires a symlink was attempted on a non-symlink file.

NotFound

A path points to a non-existent file.

IsADirectory

An operation that requires a non-directory path was attempted on a directory path.

NotADirectory

An operation that requires a directory path was attempted on a non-directory path.

IsASpecialFile

An operation that requires a regular file (or a symlink to a regular file) was attempted on a special file (fifo, character device, block device, or socket).

FileTooLarge

The file cannot be read into memory because it is too large.

NotUtf8

Data is not valid UTF-8.

MalformedPath

Data cannot be converted into a valid path.

Io(Box<dyn IoError>)

An IO operation failed. This error comes from the Ext4Read passed to Ext4::load.

Tuple Fields

0: Box<dyn IoError>

Underlying error.

Incompatible(Incompatible)

The filesystem is not supported by this library. This does not indicate a problem with the filesystem, or with the calling code. Please file a feature request and include the incompatible features.

Corrupt(Corrupt)

The filesystem is corrupt in some way.

Implementations

impl Ext4Error

pub fn as_corrupt(&self) -> Option<&Corrupt>

If the error type is Ext4Error::Corrupt, get the underlying error.

pub fn as_incompatible(&self) -> Option<&Incompatible>

If the error type is Ext4Error::Incompatible, get the underlying error.

pub fn as_io(&self) -> Option<&dyn IoError>

If the error type is Ext4Error::Io, get the underlying error.
