Reasons a bit-alphabet reduction cannot be set up or run.

Variants

PointTooNarrow

The evaluation point does not cover the coordinates one element absorbs.

Fields

needed: usize

Coordinates one packed element absorbs.

actual: usize

Coordinates the point names.

BatchWidthMismatch

The batching challenge does not name the absorbed coordinates exactly.

A shorter one would zip-truncate, dropping identity rows. Both sides move the same way, so no later check would catch it.

Fields

expected: usize

Coordinates the reduction absorbs.

actual: usize

Coordinates the challenge names.

WidthMismatch

A polynomial or point does not name the variables the reduction uses.

Fields

expected: usize

Variables the reduction runs over.

actual: usize

Variables the argument names.

RowVariables

The successor view steps within more coordinates than the point names.

Fields

row_variables: usize

Row coordinates the successor view was set up with.

num_variables: usize

Coordinates the evaluation point names.

SuccessorBatching

A batching stage for the other kind of reduction was asked for.

Fields

expected: bool

Whether the reduction sends successor elements, so its stage takes alpha.

NoSuccessorView

A successor claim was asked of a reduction set up without a successor view.

NoClaims

A batch of claims was asked for with no claim in it.

Trait Implementations

impl Eq for BitRingSwitchError

impl Error for BitRingSwitchError

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.
