Implementations

[src]

impl<Cont> GgswLevelMatrix<Cont>

[src]

pub fn from_container(

[src]

pub fn polynomial_size(&self) -> PolynomialSize

Returns the size of the polynomials of the current ciphertext.

Example

use concrete_core::crypto::ggsw::GgswLevelMatrix;
use concrete_core::crypto::GlweSize;

[src]

pub fn row_iter(
    &self
) -> impl Iterator<Item = GgswLevelRow<&[<Self as AsRefTensor>::Element]>> where

    PolynomialSize(10),
    GlweSize(7),
    DecompositionLevel(1)
);
for row in level_matrix.row_iter(){
    assert_eq!(row.glwe_size(), GlweSize(7));
    assert_eq!(row.polynomial_size(), PolynomialSize(10));
}
assert_eq!(level_matrix.row_iter().count(), 7);

[src]

pub fn row_iter_mut(
    &mut self
) -> impl Iterator<Item = GgswLevelRow<&mut [<Self as AsRefTensor>::Element]>> where
    Self: AsMutTensor,

Returns an iterator over the mutably borrowed rows of the matrix.

Example

use concrete_core::crypto::ggsw::GgswLevelMatrix;
use concrete_core::crypto::GlweSize;
use concrete_core::math::tensor::{AsMutTensor, AsRefTensor};
use concrete_core::math::polynomial::PolynomialSize;
use concrete_core::math::decomposition::DecompositionLevel;
let mut level_matrix = GgswLevelMatrix::from_container(
    vec![0 as u8; 10 * 7 * 7],
    PolynomialSize(10),
    GlweSize(7),
    DecompositionLevel(1)
);
for mut row in level_matrix.row_iter_mut(){
    row.as_mut_tensor().fill_with_element(9);
}
assert!(level_matrix.as_tensor().iter().all(|a| *a ==  9));
