Why an update was refused before any device command.

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(usize)

The image is not layout::IMAGE_SIZE bytes.

Integrity

The image fails its AES-CMAC integrity table.

DriveRead

The image is a raw drive read: its boot page is the read-back mirror, and writing it would store that page in place of the boot page.

UnknownChip

The image names no supported chip.

UnknownDriveChip

The drive’s boot banner names no supported chip generation.

ChipMismatch

The image is for another chip than the drive’s.

Fields

image: Chip

The image’s chip.

drive: Chip

The drive’s chip.

InstalledMismatch

The installed firmware is not a complete image of the live drive: its size, identity descriptor or boot banner differ.

UnknownInstalledFamily

The installed firmware does not establish a hardware family.

UnknownTargetFamily

The image does not establish a hardware family.

FamilyMismatch

The image is for other hardware than the installed firmware.

Fields

installed: Family

Family of the installed firmware.

target: Family

Family of the image.

Trait Implementations

impl Clone for PrepareError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrepareError

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

Formats the value using the given formatter.

impl Display for PrepareError

Formats the value using the given formatter.

impl Eq for PrepareError

impl Error for PrepareError

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 PrepareError

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

Equality operator ==.

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

Inequality operator !=.
