Failure while resolving an ordered sequential decision chain.

Variants

Backend(E)

The sampler or sampling backend failed.

OutOfOrder

A traversal boundary did not match the next prediction.

Fields

expected: usize

Next required prediction.

actual: usize

Traversal-supplied prediction.

predictions: usize

Total prediction count.

InvalidTailSkip

A requested tail skip was not proven safe by the plan.

Fields

prediction: usize

First proposed skipped prediction.

count: usize

Proposed skipped prediction count.

TokenDomainCountMismatch

Architecture token-domain cardinality drifted across a skipped tail.

Fields

prediction: usize

First proposed skipped prediction.

expected: usize

Expected domain count.

actual: usize

Supplied domain count.

TailBoundaryMismatch

Architecture boundary mapping disagreed within a proposed skipped tail.

Fields

expected: usize

Expected prediction ordinal.

actual: Option<usize>

Architecture-reported ordinal.

Incomplete

Traversal completed before resolving every prediction.

Fields

resolved: usize

Resolved prediction count.

predictions: usize

Planned prediction count.

Trait Implementations

impl<E: Debug> Debug for SequentialDecisionError<E>

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

Formats the value using the given formatter.

impl<E> Display for SequentialDecisionError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for SequentialDecisionError<E>

where Self: Debug + Display,

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.
