Implementations
impl<G: CurveProjective> Wnaf<(), Vec<G>, Vec<i64>>
[src]
pub fn new() -> Self
[src]
Construct a new wNAF context without allocating.
pub fn base(
&mut self,
base: G,
num_scalars: usize
) -> Wnaf<usize, &[G], &mut Vec<i64>>
[src]
&mut self,
base: G,
num_scalars: usize
) -> Wnaf<usize, &[G], &mut Vec<i64>>
Given a base and a number of scalars, compute a window table and return a Wnaf
object that
can perform exponentiations with .scalar(..)
.
pub fn scalar(
&mut self,
scalar: <<G as CurveProjective>::Scalar as PrimeField>::Repr
) -> Wnaf<usize, &mut Vec<G>, &[i64]>
[src]
&mut self,
scalar: <<G as CurveProjective>::Scalar as PrimeField>::Repr
) -> Wnaf<usize, &mut Vec<G>, &[i64]>
Given a scalar, compute its wNAF representation and return a Wnaf
object that can perform
exponentiations with .base(..)
.
impl<'a, G: CurveProjective> Wnaf<usize, &'a [G], &'a mut Vec<i64>>
[src]
pub fn shared(&self) -> Wnaf<usize, &'a [G], Vec<i64>>
