Struct BaseTester 

Source 
pub struct BaseTester { /* private fields */ }
Expand description

Helper to facilitate easier writing of tests using RangeChip and RangeCircuitBuilder. By default, the MockProver is used.

Currently this tester uses all private inputs.

Implementations§

Source§

impl BaseTester

Source

pub fn k(self, k: u32) -> Self

Changes the number of rows in the circuit to 2k. By default it will also set lookup bits as large as possible, to k - 1.

Source

pub fn lookup_bits(self, lookup_bits: usize) -> Self

Sets the size of the lookup table used for range checks to [0, 2lookup_bits)

Source

pub fn expect_satisfied(self, expect_satisfied: bool) -> Self

Specify whether you expect this test to pass or fail. Default: pass

Source

pub fn unusable_rows(self, unusable_rows: usize) -> Self

Set the number of blinding (poisoned) rows

Source

pub fn run<R>(&self, f: impl FnOnce(&mut Context<Fr>, &RangeChip<Fr>) -> R) -> R

Run a mock test by providing a closure that uses a ctx and RangeChip.

  • expect_satisfied: flag for whether you expect the test to pass or fail. Failure means a constraint system failure – the tester does not catch system panics.
Source

pub fn run_gate<R>( &self, f: impl FnOnce(&mut Context<Fr>, &GateChip<Fr>) -> R, ) -> R

Run a mock test by providing a closure that uses a ctx and GateChip.

  • expect_satisfied: flag for whether you expect the test to pass or fail. Failure means a constraint system failure – the tester does not catch system panics.
Source

pub fn run_builder<R>( &self, f: impl FnOnce(&mut SinglePhaseCoreManager<Fr>, &RangeChip<Fr>) -> R, ) -> R

Run a mock test by providing a closure that uses a builder and RangeChip.

Source

pub fn bench_builder<I: Clone>( &self, init_input: I, logic_input: I, f: impl Fn(&mut SinglePhaseCoreManager<Fr>, &RangeChip<Fr>, I), ) -> BenchStats

Runs keygen, real prover, and verifier by providing a closure that uses a builder and RangeChip.

Must provide init_input for use during key generation, which is preferably not equal to logic_input. These are the inputs to the closure, not necessary public inputs to the circuit.

Currently for testing, no public instances.
