Implementations

impl LookupTable

pub fn entries<F: PrimeField>(&self, domain_d1_size: u64) -> Option<Vec<F>>

Provides a full list of entries for the given table.

pub fn is_member<F: PrimeField>(&self, value: F) -> Option<bool>

Checks if a value is in a given table.

Trait Implementations

impl Clone for LookupTable

fn clone(&self) -> LookupTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LookupTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for LookupTable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoEnumIterator for LookupTable

type Iterator = LookupTableIter

fn iter() -> LookupTableIter

impl LookupTableID for LookupTable

fn ix_by_value<F: PrimeField>(&self, value: &[F]) -> Option<usize>

Converts a value to its index in the fixed table.

fn to_u32(&self) -> u32

Assign a unique ID, as a u32 value

fn from_u32(value: u32) -> Self

Build a value from a u32

fn is_fixed(&self) -> bool

Identify fixed and RAMLookups with a boolean. This can be used to identify the lookups whose table values are fixed, like range checks.

fn runtime_create_column(&self) -> bool

If a table is runtime table, true means we should create an explicit extra column for it to “read” from. false means that this table will be reading from some existing (e.g. relation) columns, and no extra columns should be added.

fn length(&self) -> usize

Returns the length of each table.

fn all_variants() -> Vec<Self>

fn to_field<F: Field>(&self) -> F

Assign a unique ID to the lookup tables.

fn to_constraint<F: Field>(&self) -> E<F>

Assign a unique ID to the lookup tables, as an expression.

impl Ord for LookupTable

fn cmp(&self, other: &LookupTable) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LookupTable

fn eq(&self, other: &LookupTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for LookupTable

fn partial_cmp(&self, other: &LookupTable) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
