Enum PropagationError 

#[non_exhaustive]
pub enum PropagationError {
    NodeOutOfRange,
    RoundAlreadyRunning,
    RoundNotRunning,
    NodeAlreadyUpdated,
    RoundIncomplete,
    PassTerminated,
    PassStillRunning,
}

A disabled propagation transition.

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.

NodeOutOfRange

A node index is outside the admitted graph.

RoundAlreadyRunning

A round is already running.

RoundNotRunning

The operation requires a running round.

NodeAlreadyUpdated

The node has already committed its update in this round.

RoundIncomplete

Not every node has committed an update.

PassTerminated

The pass is settled or has exhausted its iteration ceiling.

PassStillRunning

The pass is not yet settled and has not reached its ceiling.

impl Eq for PropagationError

impl Error for PropagationError

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 PropagationError

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

Equality operator ==.

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

Inequality operator !=.
