pub struct LookupRangeCheckConfig<F: FieldExt + PrimeFieldBits, const K: usize> { /* private fields */ }
Expand description
Configuration that provides methods for a lookup range check.
Implementations
sourceimpl<F: FieldExt + PrimeFieldBits, const K: usize> LookupRangeCheckConfig<F, K>
impl<F: FieldExt + PrimeFieldBits, const K: usize> LookupRangeCheckConfig<F, K>
sourcepub fn configure(
meta: &mut ConstraintSystem<F>,
running_sum: Column<Advice>,
table_idx: TableColumn
) -> Self
pub fn configure(
meta: &mut ConstraintSystem<F>,
running_sum: Column<Advice>,
table_idx: TableColumn
) -> Self
The running_sum
advice column breaks the field element into K
-bit
words. It is used to construct the input expression to the lookup
argument.
The table_idx
fixed column contains values from [0..2^K). Looking up
a value in table_idx
constrains it to be within this range. The table
can be loaded outside this helper.
Side-effects
Both the running_sum
and constants
columns will be equality-enabled.
sourcepub fn copy_check(
&self,
layouter: impl Layouter<F>,
element: AssignedCell<F, F>,
num_words: usize,
strict: bool
) -> Result<RunningSum<F>, Error>
pub fn copy_check(
&self,
layouter: impl Layouter<F>,
element: AssignedCell<F, F>,
num_words: usize,
strict: bool
) -> Result<RunningSum<F>, Error>
Range check on an existing cell that is copied into this helper.
Returns an error if element
is not in a column that was passed to
[ConstraintSystem::enable_equality
] during circuit configuration.
sourcepub fn witness_check(
&self,
layouter: impl Layouter<F>,
value: Value<F>,
num_words: usize,
strict: bool
) -> Result<RunningSum<F>, Error>
pub fn witness_check(
&self,
layouter: impl Layouter<F>,
value: Value<F>,
num_words: usize,
strict: bool
) -> Result<RunningSum<F>, Error>
Range check on a value that is witnessed in this helper.
sourcepub fn copy_short_check(
&self,
layouter: impl Layouter<F>,
element: AssignedCell<F, F>,
num_bits: usize
) -> Result<(), Error>
pub fn copy_short_check(
&self,
layouter: impl Layouter<F>,
element: AssignedCell<F, F>,
num_bits: usize
) -> Result<(), Error>
Short range check on an existing cell that is copied into this helper.
Panics
Panics if NUM_BITS is equal to or larger than K.
sourcepub fn witness_short_check(
&self,
layouter: impl Layouter<F>,
element: Value<F>,
num_bits: usize
) -> Result<AssignedCell<F, F>, Error>
pub fn witness_short_check(
&self,
layouter: impl Layouter<F>,
element: Value<F>,
num_bits: usize
) -> Result<AssignedCell<F, F>, Error>
Short range check on value that is witnessed in this helper.
Panics
Panics if num_bits is larger than K.
