Failure while exchanging or validating complete rank-local manifests.

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.

EmptyTopology

A consensus topology cannot be empty.

MetadataOverflow(&'static str)

Portable metadata exceeded its wire or host representation.

Encoding(String)

The local manifest could not be encoded.

Transport(String)

The control-plane collective failed.

MalformedGather

An equal-word gather returned a malformed rank-major frame.

Fields

stage: &'static str

Protocol stage being gathered.

expected: usize

Expected gathered word count.

actual: usize

Actual gathered word count.

participants: usize

Expected participant count.

PayloadLengthOverflow

A peer encoded a payload length that this host cannot represent.

Fields

rank: usize

Rank that advertised the length.

length: u64

Advertised encoded byte length.

InvalidPayloadLength

A peer advertised more bytes than fit in the gathered padded frame.

Fields

rank: usize

Rank that advertised the invalid length.

length: usize

Advertised encoded byte length.

available: usize

Bytes available in one gathered rank frame.

InvalidEncoding

A peer payload was not a valid checked opaque manifest.

Fields

rank: usize

Rank whose payload failed decoding or checked construction.

message: String

Serialization or manifest validation detail.

Manifest(CommunicationManifestError)

The reconstructed rank manifests are not mutually compatible.

Trait Implementations

impl Clone for CommunicationManifestConsensusError

fn clone(&self) -> CommunicationManifestConsensusError

impl Eq for CommunicationManifestConsensusError

impl Error for CommunicationManifestConsensusError

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
