}

Standard error codes.

Variants

UnsupportedVersion

We found a header in the flash that we don’t support

CorruptData

Some of the data in flash appears to be corrupt

InvalidCheckSum

The check sum doesn’t match Note that the value buffer is still filled

KeyNotFound

The requested key couldn’t be found

KeyAlreadyExists

Indicates that we can’t add this key as one with the same key hash already exists.

RegionFull

Indicates that the region where this object should be added is full. In future this error should be handled internally by allocating the object in a different region.

FlashFull

Unable to add a key, the flash is full. Note that the flash might not be full after running a garbage collection.

ReadFail

Unable to read the flash region

WriteFail

Unable to write the buffer to the flash address

EraseFail

Unable to erase the flash region

ObjectTooLarge

The object is larger then 0x7FFF

BufferTooSmall(usize)

The supplied buffer is too small. The error code includes the total length of the value.

ReadNotReady(usize)

Indicates that the flash read operation is not yet ready. The process can be retried by calling continue_operation().

WriteNotReady(usize)

Indicates that the flash write operation is not yet ready.

EraseNotReady(usize)

Indicates that the flash erase operation is not yet ready.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl From<ErrorCode> for isize

fn from(original: ErrorCode) -> isize

Converts to this type from the input type.

impl From<ErrorCode> for usize

fn from(original: ErrorCode) -> usize

Converts to this type from the input type.

impl PartialEq for ErrorCode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
