Failure to read a UBI image whose source fails with E.

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.

Size(E)

Reading the size of the image failed.

Read

Reading a block failed.

Fields

block: u32

The index of the block.

source: E

The error of the source.

PartialBlock

The image ends in the middle of a block.

Fields

block: u32

The index of the block.

len: usize

The bytes of the block in the image.

Header

A block of the image has an invalid header.

Fields

block: u32

The index of the block.

source: FormatError

The error of the header.

Offsets

The header offsets don’t fit the block, or no minimum I/O size gives this data offset.

Fields

vid_header_offset: u32

The offset of the volume identifier header.

data_offset: u32

The offset of the data.

block_size: usize

The size of the block.

TooManyBlocks

The image has more blocks than fit into a u32.

BufferLength

A buffer or block map has the wrong length.

Fields

len: usize

The length of the buffer.

needed: usize

The length that the buffer needs.

NoVolumeTable

The image holds data, but no volume table.

VolumeTable

Neither copy of the volume table is valid.

Fields

lnum: u32

The logical eraseblock of the last copy that was checked.

source: FormatError

The error of that copy.

DuplicateBlock

Blocks with the same logical eraseblock have the same sequence number.

Fields

first: u32

The index of the first block.

second: u32

The index of the second block.

MissingBlock

A static volume misses a logical eraseblock.

Fields

lnum: u32

The number of the logical eraseblock.

UpdateMarker

The volume has an update that didn’t finish. The kernel refuses to read it.

Trait Implementations

impl<E: Debug> Debug for ImageError<E>

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

Formats the value using the given formatter.

impl<E> Display for ImageError<E>

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

Formats the value using the given formatter.

impl<E> Error for ImageError<E>

where E: Error + 'static, Self: Debug + Display,

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.
