Struct BatchMulPreprocessing 

Source 
pub struct BatchMulPreprocessing<T: ScalarMul> {
    pub window: usize,
    pub max_scalar_size: usize,
    pub table: Vec<Vec<T::MulBase>>,
}
Expand description

Preprocessing used internally for batch scalar multiplication via ScalarMul::batch_mul.

  • window is the window size used for the precomputation
  • max_scalar_size is the maximum size of the scalars that will be multiplied
  • table is the precomputed table of multiples of base
