Invalid UBI header or volume table record.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Truncated

The data ends before the end of the header.

Fields

len: usize

The length of the data.

Magic

The header doesn’t start with the magic number of its type.

Fields

found: u32

The magic number in the data.

Version(u8)

The header has a version this crate doesn’t know.

Crc

A stored CRC doesn’t match the data it covers.

Fields

stored: u32

The CRC stored in the header.

computed: u32

The CRC computed from the header.

Field

A field has a value that the kernel rejects.

Fields

name: &'static str

The name of the field, as in the kernel’s ubi-media.h.

value: u64

The value of the field.

UnusedRecord

A volume table record without reserved blocks has other fields set.

VolumeName

The volume name is invalid. The kernel accepts 1 to 127 bytes without a NUL byte, followed by a NUL byte.

DuplicateName

A volume in the volume table has the name of an earlier volume.

Fields

first: u32

The ID of the first volume.

second: u32

The ID of the second volume.

MultipleAutoresize

A volume table has more than one volume with the autoresize flag.

Fields

first: u32

The ID of the first volume.

second: u32

The ID of the second volume.

Trait Implementations

impl Clone for FormatError

fn clone(&self) -> FormatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Eq for FormatError

impl Error for FormatError

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.

impl PartialEq for FormatError

fn eq(&self, other: &FormatError) -> bool

Equality operator ==.

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

Inequality operator !=.
