Errors encountered by decds during blob building and repairing.

Variants

EmptyDataForBlob

Returned when trying to create a blob with empty data.

InvalidStartBound

Returned when a byte range operation has an invalid start bound.

InvalidEndBound(usize)

Returned when a byte range operation has an invalid end bound. Contains the invalid end value.

BlobHeaderSerializationFailed(String)

Returned when BlobHeader serialization fails. Contains the error message from the underlying serialization library.

BlobHeaderDeserializationFailed(String)

Returned when BlobHeader deserialization fails. Contains the error message from the underlying deserialization library.

ProofCarryingChunkSerializationFailed(String)

Returned when ProofCarryingChunk serialization fails. Contains the error message from the underlying serialization library.

ProofCarryingChunkDeserializationFailed(String)

Returned when ProofCarryingChunk deserialization fails. Contains the error message from the underlying deserialization library.

ChunksetReadyToRepair(usize)

Returned when attempting to add a chunk to a RepairingChunkSet that is already ready for repair. Contains the chunkset ID.

ChunksetNotYetReadyToRepair(usize)

Returned when attempting to repair a RepairingChunkSet that is not yet ready. Contains the chunkset ID.

ChunksetAlreadyRepaired(usize)

Returned when attempting to add a chunk to a RepairingChunkSet that has already been repaired. Contains the chunkset ID.

ChunksetRepairingFailed(usize, String)

Returned when RepairingChunkSet fails to repair its data. Contains the chunkset ID and an error message.

InvalidErasureCodedShareId(usize)

Returned when an invalid erasure-coded share ID is provided. Contains the invalid share ID.

InvalidChunksetId(usize, usize)

Returned when an invalid chunkset ID is provided. Contains the invalid chunkset ID and the total number of chunksets.

InvalidChunksetSize(usize)

Returned when creating a ChunkSet with data of an invalid size. Contains the provided size.

InvalidChunkMetadata(usize)

Returned when a chunk contains metadata (e.g., chunkset ID) that does not match the expected context. Contains the chunkset ID.

InvalidProofInChunk(usize)

Returned when a ProofCarryingChunk fails its Merkle proof validation. Contains the chunkset ID.

ChunkDecodingFailed(usize, String)

Returned when decoding a chunk fails during the repair process. Contains the chunkset ID and an error message.

NoLeafNodesToBuildMerkleTreeOn

Returned when attempting to build a Merkle tree with no leaf nodes.

InvalidLeafNodeIndex(usize, usize)

Returned when a Merkle tree operation specifies an invalid leaf node index. Contains the invalid index and the total number of leaves.

Trait Implementations

impl Debug for DecdsError

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

Formats the value using the given formatter.

impl Display for DecdsError

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

Formats the value using the given formatter.

impl Error for DecdsError

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 DecdsError

fn eq(&self, other: &DecdsError) -> 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.
