Expand description

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

§

NotFound

That file or directory 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

§

DeleteNonEmptyDir

You can’t delete a non-empty directory

§

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

Tried to create an existing file

§

BadBlockSize(u16)

Bad block size - only 512 byte blocks supported

§

InvalidOffset

Bad offset given when seeking

§

DiskFull

Disk is full

§

DirAlreadyExists

A directory with that name already exists

§

LockError

The filesystem tried to gain a lock whilst already locked.

This is either a bug in the filesystem, or you tried to access the filesystem API from inside a directory iterator (that isn’t allowed).
