Errors that can occur during Horon operations.

Variants

Io(Error)

File I/O error.

InvalidFormat(String)

Invalid .htt file (bad magic, unsupported version, corrupted header).

ChecksumMismatch

CRC mismatch on header, snapshot entry, or WAL entry.

Fields

expected: u32

CRC32 value recorded in the file.

actual: u32

CRC32 value computed over the bytes actually read.

context: String

Which structure the mismatch was detected in (e.g. “header”, “WAL entry”).

CorruptedWalEntry

WAL entry is corrupted (partial write detected during recovery).

Fields

seq: u32

Sequence number of the corrupted entry.

message: String

Description of what was wrong with the entry.

UnsupportedCompression(u8)

Unsupported compression algorithm.

CompressionError(String)

Compression/decompression failure.

Store(StoreError)

engine Store error (passthrough).

AccessDenied

Access denied by geometric ACL.

Fields

key: String

Key of the node the requester attempted to access.

reason: String

Why access was refused (which band check failed).

Config(String)

Configuration error.

Locked(String)

The file is already open (advisory-locked) by another process.

InvalidOperation(String)

The requested write cannot be represented in the on-disk format (e.g. key longer than the u16 length field allows).

Trait Implementations

impl Debug for HoronError

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

Formats the value using the given formatter.

impl Display for HoronError

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

Formats the value using the given formatter.

impl Error for HoronError

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 From<Error> for HoronError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<StoreError> for HoronError

fn from(e: StoreError) -> Self

Converts to this type from the input type.
