Expand description

The reasons why a particular circuit is not satisfied.

Variants§

§

CellNotAssigned

A cell used in an active gate was not assigned to.

Fields

§gate: Gate

The index of the active gate.

§region: Region

The region in which this cell should be assigned.

§gate_offset: usize

The offset (relative to the start of the region) at which the active gate queries this cell.

§column: Column<Any>

The column in which this cell should be assigned.

§offset: isize

The offset (relative to the start of the region) at which this cell should be assigned. This may be negative (for example, if a selector enables a gate at offset 0, but the gate uses Rotation::prev()).

§

InstanceCellNotAssigned

An instance cell used in an active gate was not assigned to.

Fields

§gate: Gate

The index of the active gate.

§region: Region

The region in which this gate was activated.

§gate_offset: usize

The offset (relative to the start of the region) at which the active gate queries this cell.

§column: Column<Instance>

The column in which this cell should be assigned.

§row: usize

The absolute row at which this cell should be assigned.

§

ConstraintNotSatisfied

A constraint was not satisfied for a particular row.

Fields

§constraint: Constraint

The polynomial constraint that is not satisfied.

§location: FailureLocation

The location at which this constraint is not satisfied.

FailureLocation::OutsideRegion is usually caused by a constraint that does not contain a selector, and as a result is active on every row.

§cell_values: Vec<(VirtualCell, String)>

The values of the virtual cells used by this constraint.

§

ConstraintPoisoned

A constraint was active on an unusable row, and is likely missing a selector.

Fields

§constraint: Constraint

The polynomial constraint that is not satisfied.

§

Lookup

A lookup input did not exist in its corresponding table.

Fields

§lookup_index: usize

The index of the lookup that is not satisfied. These indices are assigned in the order in which ConstraintSystem::lookup is called during Circuit::configure.

§location: FailureLocation

The location at which the lookup is not satisfied.

FailureLocation::InRegion is most common, and may be due to the intentional use of a lookup (if its inputs are conditional on a complex selector), or an unintentional lookup constraint that overlaps the region (indicating that the lookup’s inputs should be made conditional).

FailureLocation::OutsideRegion is uncommon, and could mean that:

  • The input expressions do not correctly constrain a default value that exists in the table when the lookup is not being used.
  • The input expressions use a column queried at a non-zero Rotation, and the lookup is active on a row adjacent to an unrelated region.
§

Permutation

A permutation did not preserve the original value of a cell.

Fields

§column: Column

The column in which this permutation is not satisfied.

§location: FailureLocation

The location at which the permutation is not satisfied.
