Enum Slot 

pub enum Slot {
    Arg(ArgNo),
    Output(OutputId),
    Advice(CellRef),
    Fixed(CellRef),
    TableLookup(u64, usize, usize, usize, usize),
    CallOutput(usize, usize),
    Temp(usize),
    Challenge(usize, u8, ArgNo),
}

A slot represents storage locations in a circuit.

A slot can represent IO (Arg, Output, Challenge, …) or cells in the PLONK table (Advice, Fixed, TableLookup).

Variants

Arg(ArgNo)

Points to the n-th input argument

Output(OutputId)

Points to the n-th output.

Advice(CellRef)

Points to an advice cell.

Fixed(CellRef)

Points to a fixed cell.

TableLookup(u64, usize, usize, usize, usize)

lookup id, column, row, idx, region_idx

CallOutput(usize, usize)

call output: (call #, output #)

Temp(usize)

Temporary value

Challenge(usize, u8, ArgNo)

Challenge argument (index, phase, n-th arg)

Implementations

impl Slot

pub fn advice_rel(col: usize, base: usize, offset: usize) -> Self

Creates the Slot::Advice case using relative coordinates.

See CellRef::relative for more details.

pub fn fixed_abs(col: usize, row: usize) -> Self

Creates the Slot::Fixed case using absolute coordinates.

See CellRef::absolute for more details.

pub fn fixed_rel(col: usize, base: usize, offset: usize) -> Self

Creates the Slot::Fixed case using relative coordinates.

See CellRef::relative for more details.

Trait Implementations

impl Clone for Slot

fn clone(&self) -> Slot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slot

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

Formats the value using the given formatter.

impl Display for Slot

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

Formats the value using the given formatter.

impl EqvRelation<Slot> for SymbolicEqv

fn equivalent(lhs: &Slot, rhs: &Slot) -> bool

Two Slots are symbolically equivalent if they refer to the same data regardless of how is pointed to.

Arguments and fields: equivalent if they refer to the same offset. Advice and fixed cells: equivalent if they point to the same cell relative to their base. Table lookups: equivalent if they point to the same column and row. Call outputs: equivalent if they have the same output number.

impl From<ArgNo> for Slot

fn from(value: ArgNo) -> Self

Converts to this type from the input type.

impl From<OutputId> for Slot

fn from(value: OutputId) -> Self

Converts to this type from the input type.

impl Hash for Slot

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 Ord for Slot

fn cmp(&self, other: &Slot) -> 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 Slot

fn eq(&self, other: &Slot) -> 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 Slot

fn partial_cmp(&self, other: &Slot) -> 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.
