Struct Selector 

pub struct Selector { /* private fields */ }

Identifies one slot inside the stacked polynomial.

Implementations

impl Selector

pub const fn new(num_variables: usize, index: usize) -> Self

Builds a selector over num_variables bits pointing at slot index.

Panics

• Slot index must fit in num_variables bits.

pub fn point<F: Field>(&self) -> Point<F>

Returns the hypercube point that addresses this slot.

pub const fn num_variables(&self) -> usize

Returns the number of selector bits.

pub const fn index(&self) -> usize

Returns the slot index.

pub const fn reverse(&mut self)

Returns this selector with its bitstring reversed.

pub fn lift_prefix<Ext: Field>(&self, other: &Point<Ext>) -> Point<Ext>

Prefixes other with the selector bits.

pub fn lift_suffix<Ext: Field>(&self, other: &Point<Ext>) -> Point<Ext>

Appends the selector bits after the local coordinates.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Selector

impl Debug for Selector

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

Formats the value using the given formatter.
