Structured consensus validation failure without backend error types.

Variants

EmptyTopology

A consensus topology cannot be empty.

MetadataOverflow(&'static str)

Portable metadata exceeded its wire representation.

Transport(String)

The backend collective failed.

MalformedGather

The transport returned a malformed rank-major gather.

Fields

expected: usize

Expected gathered word count.

actual: usize

Actual gathered word count.

participants: usize

Expected participant count.

Mismatch

A schedule or disposition frame differed.

Fields

context: &'static str

Operation being validated.

rank: usize

First disagreeing rank.

CompletionHeader

Completion protocol, work count, or frame size differed.

Fields

rank: usize

First disagreeing rank.

CompletionIdentity

Completion work ordering differed.

Fields

rank: usize

First disagreeing rank.

CompletionStatus

A rank emitted an unknown completion status.

Fields

rank: usize

First rank with an invalid value.

Trait Implementations

impl Clone for ConsensusError

fn clone(&self) -> ConsensusError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsensusError

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

Formats the value using the given formatter.

impl Display for ConsensusError

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

Formats the value using the given formatter.

impl Eq for ConsensusError

impl Error for ConsensusError

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 ConsensusError

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

Equality operator ==.

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

Inequality operator !=.
