Failure of an MTD operation.

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.

PartitionTable(Error)

Reading the partition table in /proc/mtd failed.

PartitionEntry

A line in /proc/mtd isn’t a valid partition entry.

Fields

line: String

The line that failed to parse.

PartitionNotFound

No MTD partition has the requested name.

Fields

name: String

The requested name.

Open

Opening a device file failed.

Fields

path: PathBuf

The device file.

source: Error

The error of the open call.

Info(Error)

Querying the geometry of the MTD device failed.

Geometry

The MTD device reports a geometry this crate can’t handle.

Fields

size: u64

The size of the device in bytes.

block_size: u32

The erase block size in bytes.

page_size: u32

The page size in bytes.

BlockOutOfRange

The block is beyond the end of the device.

Fields

block: u32

The requested block.

BufferLength

A buffer exceeds a block, or a write buffer doesn’t end on a page.

Fields

len: usize

The length of the buffer.

BadBlockCheck

Checking a block for the bad block marker failed.

Fields

block: u32

The checked block.

source: Error

The error of the ioctl.

MarkBad

Marking a block bad failed.

Fields

block: u32

The block to mark.

source: Error

The error of the ioctl.

Erase

Erasing a block failed.

Fields

block: u32

The block to erase.

source: Error

The error of the ioctl.

Read

Reading a block failed.

Fields

block: u32

The block to read.

source: Error

The error of the read.

Uncorrectable

A block contains bit errors that ECC can’t correct.

Fields

block: u32

The block that was read.

Write

Writing a block failed.

Fields

block: u32

The block to write.

source: Error

The error of the write.

Verify

A block doesn’t contain the data that was written to it.

Fields

block: u32

The written block.

NoSpace

No good block is left on the device.

Implementations

impl DeviceError

pub(crate) fn is_media_failure(&self) -> bool

Returns whether the error means that the block itself is failing.

Trait Implementations

impl Debug for DeviceError

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

Formats the value using the given formatter.

impl Display for DeviceError

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

Formats the value using the given formatter.

impl Error for DeviceError

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.
