Errors from DHT operations.

Variants

Krpc

Remote node returned a KRPC error response.

Fields

code: i64

KRPC error code (e.g. 201 = generic, 203 = method unknown).

message: String

Human-readable error description.

InvalidMessage(String)

Received a malformed KRPC message.

TransactionMismatch

Response transaction ID does not match the request.

Fields

expected: u16

Expected transaction ID.

got: u16

Received transaction ID.

Timeout

Query timed out with no response.

InvalidCompactNode(String)

Malformed compact node info bytes.

RoutingTableFull

All k-buckets are full and no stale nodes to replace.

Shutdown

DHT actor has been shut down.

Bencode(Error)

Bencode parsing error.

Io(Error)

I/O error.

Bep44ValueTooLarge

BEP 44 value exceeds the 1000-byte limit.

Fields

size: usize

Actual value size in bytes.

max: usize

Maximum allowed size.

Bep44SaltTooLarge

BEP 44 salt exceeds the 64-byte limit.

Fields

size: usize

Actual salt size in bytes.

max: usize

Maximum allowed size.

Bep44InvalidSignature

BEP 44 ed25519 signature verification failed.

Bep44SequenceTooOld

BEP 44 put rejected because sequence number is not newer.

Fields

got: i64

Sequence number in the put request.

current: i64

Current stored sequence number.

Bep44CasMismatch

BEP 44 CAS (compare-and-swap) failed because stored seq differs.

Fields

expected: i64

Expected sequence number from the CAS field.

actual: i64

Actual stored sequence number.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
