Expand description

Represents all the ways the functions in this crate can fail.

Variants§

DeviceError(E)

The underlying block device threw an error.

FormatError(&'static str)

The filesystem is badly formatted (or this code is buggy).

NoSuchVolume

The given VolumeIdx was bad,

FilenameError(FilenameError)

The given filename was bad

TooManyOpenVolumes

Out of memory opening volumes

TooManyOpenDirs

Out of memory opening directories

TooManyOpenFiles

Out of memory opening files

BadHandle

Bad handle given

FileNotFound

That file doesn’t exist

FileAlreadyOpen

You can’t open a file twice or delete an open file

DirAlreadyOpen

You can’t open a directory twice

OpenedDirAsFile

You can’t open a directory as a file

OpenedFileAsDir

You can’t open a file as a directory

DeleteDirAsFile

You can’t delete a directory as a file

VolumeStillInUse

You can’t close a volume with open files or directories

VolumeAlreadyOpen

You can’t open a volume twice

Unsupported

We can’t do that yet

EndOfFile

Tried to read beyond end of file

BadCluster

Found a bad cluster

ConversionError

Error while converting types

NotEnoughSpace

The device does not have enough space for the operation

AllocationError

Cluster was not properly allocated by the library

UnterminatedFatChain

Jumped to free space during FAT traversing

ReadOnly

Tried to open Read-Only file with write mode

FileAlreadyExists

BadBlockSize(u16)

Bad block size - only 512 byte blocks supported

InvalidOffset

Bad offset given when seeking
