Struct VariableRangeCheckerChip 

pub struct VariableRangeCheckerChip {
    pub air: VariableRangeCheckerAir,
    pub count: Vec<AtomicU32>,
}

Fields

air: VariableRangeCheckerAir

count: Vec<AtomicU32>

Implementations

impl VariableRangeCheckerChip

pub fn new(bus: VariableRangeCheckerBus) -> Self

pub fn bus(&self) -> VariableRangeCheckerBus

pub fn range_max_bits(&self) -> usize

pub fn air_width(&self) -> usize

pub fn add_count(&self, value: u32, max_bits: usize)

pub fn clear(&self)

pub fn generate_trace<F: Field>(&self) -> RowMajorMatrix<F>

Generates trace and resets the internal counters all to 0.

pub fn decompose<F: Field>(&self, value: u32, bits: usize, limbs: &mut [F])

Range checks that value is bits bits by decomposing into limbs where all but last limb is range_max_bits bits. Assumes there are enough limbs.

Trait Implementations

impl<R, SC: StarkGenericConfig> Chip<R, CpuBackend<SC>> for VariableRangeCheckerChip

where Val<SC>: PrimeField32,

fn generate_proving_ctx(&self, _: R) -> AirProvingContext<CpuBackend<SC>>

Generates trace and resets the internal counters all to 0.

impl ChipUsageGetter for VariableRangeCheckerChip

fn air_name(&self) -> String

fn constant_trace_height(&self) -> Option<usize>

If the chip has a state-independent trace height that is determined upon construction, return this height. This is used to distinguish “static” versus “dynamic” usage metrics.

fn current_trace_height(&self) -> usize

Height of used rows in the main trace.

fn trace_width(&self) -> usize

Width of the main trace

fn current_trace_cells(&self) -> usize

For metrics collection
