Trait Implementations§
source§impl<F: Field> Circuit<F> for TxCircuit<F>
impl<F: Field> Circuit<F> for TxCircuit<F>
§type Config = (TxCircuitConfig<F>, Challenges, KeccakTable)
type Config = (TxCircuitConfig<F>, Challenges, KeccakTable)
This is a configuration object that stores things like columns.
§type FloorPlanner = SimpleFloorPlanner
type FloorPlanner = SimpleFloorPlanner
The floor planner used for this circuit. This is an associated type of the
Circuit
trait because its behaviour is circuit-critical.source§fn without_witnesses(&self) -> Self
fn without_witnesses(&self) -> Self
Returns a copy of this circuit with no witness values (i.e. all witnesses set to
None
). For most circuits, this will be equal to Self::default()
.source§fn configure(meta: &mut ConstraintSystem<F>) -> Self::Config
fn configure(meta: &mut ConstraintSystem<F>) -> Self::Config
The circuit is given an opportunity to describe the exact gate
arrangement, column arrangement, etc.
source§fn synthesize(
&self,
(config, challenges, keccak_table): Self::Config,
layouter: impl Layouter<F>
) -> Result<(), Error>
fn synthesize( &self, (config, challenges, keccak_table): Self::Config, layouter: impl Layouter<F> ) -> Result<(), Error>
Given the provided
cs
, synthesize the circuit. The concrete type of
the caller will be different depending on the context, and they may or
may not expect to have a witness present.§fn params(&self) -> Self::Params
fn params(&self) -> Self::Params
Returns a reference to the parameters that should be used to configure the circuit.
Requires the
circuit-params
feature.§fn configure_with_params(
meta: &mut ConstraintSystem<F>,
_params: Self::Params
) -> Self::Config
fn configure_with_params( meta: &mut ConstraintSystem<F>, _params: Self::Params ) -> Self::Config
The circuit is given an opportunity to describe the exact gate
arrangement, column arrangement, etc. Takes a runtime parameter. The default
implementation calls
configure
ignoring the _params
argument in order to easily support
circuits that don’t use configuration parameters.source§impl<F: Field> SubCircuit<F> for TxCircuit<F>
impl<F: Field> SubCircuit<F> for TxCircuit<F>
source§fn min_num_rows_block(block: &Block<F>, chunk: &Chunk<F>) -> (usize, usize)
fn min_num_rows_block(block: &Block<F>, chunk: &Chunk<F>) -> (usize, usize)
Return the minimum number of rows required to prove the block
source§fn synthesize_sub(
&self,
config: &Self::Config,
challenges: &Challenges<Value<F>>,
layouter: &mut impl Layouter<F>
) -> Result<(), Error>
fn synthesize_sub( &self, config: &Self::Config, challenges: &Challenges<Value<F>>, layouter: &mut impl Layouter<F> ) -> Result<(), Error>
Make the assignments to the TxCircuit
§type Config = TxCircuitConfig<F>
type Config = TxCircuitConfig<F>
Configuration of the SubCircuit.
source§fn unusable_rows() -> usize
fn unusable_rows() -> usize
Returns number of unusable rows of the SubCircuit, which should be
meta.blinding_factors() + 1
.source§fn new_from_block(block: &Block<F>, chunk: &Chunk<F>) -> Self
fn new_from_block(block: &Block<F>, chunk: &Chunk<F>) -> Self
Create a new SubCircuit from a witness Block
