Struct Table 

pub struct Table<E: ElementExt>(usize, Vec<E>);

Available on crate feature alloc only.

A table to perform multiplications with.

Tuple Fields

0: usize

1: Vec<E>

Implementations

impl<E: ElementExt> Table<E>

pub fn new(bits: u32, identity: E, element: E) -> Self

Create a new table.

This function executes in constant-time w.r.t. element if double, add are constant-time.

pub fn new_for_scalar_bits(scalar_bits: usize, identity: E, element: E) -> Self

Create a new table of size optimal for a scalar-length.

This is usable in ad-hoc multiplications where creating the table, and performing the multiplication with it, should not cost more than performing the multiplication out-right.

pub fn bits(&self) -> usize

The bits preprocessed by this table.

Trait Implementations

impl<E: ElementExt> AsRef<[E]> for Table<E>

fn as_ref(&self) -> &[E]

Converts this type into a shared reference of the (usually inferred) input type.

impl<E: Clone + ElementExt> Clone for Table<E>

fn clone(&self) -> Table<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: ElementExt> Index<usize> for Table<E>

type Output = E

The returned type after indexing.

fn index(&self, i: usize) -> &E

Performs the indexing (container[index]) operation.
