Struct LweBootstrapKeyView64 

pub struct LweBootstrapKeyView64<'a>(/* private fields */);

A structure representing an LWE bootstrap key with 64 bits of precision.

By view here, we mean that the entity does not own the data, but immutably borrows it.

Notes:

This view is not Clone as Clone for a slice is not defined. It is not Deserialize either, as Deserialize of a slice is not defined. Immutable variant.

Example:

let polynomial_size = PolynomialSize(256);

// Unix seeder must be given a secret input.
// Here we just give it 0, which is totally unsafe.
const UNSAFE_SECRET: u128 = 0;
let mut engine = DefaultEngine::new(Box::new(UnixSeeder::new(UNSAFE_SECRET)))?;

assert_eq!(slice, retrieved_slice);

unsafe fn consume_retrieve_lwe_bootstrap_key_unchecked( &mut self, bootstrap_key: LweBootstrapKeyView64<'data>, ) -> &'data [u64]

Unsafely retrieves the content of the container from an LWE bootstrap key, consuming it in the process.

Unsafely creates an LWE bootstrap key from an existing container.

impl LweBootstrapKeyEntity for LweBootstrapKeyView64<'_>

fn glwe_dimension(&self) -> GlweDimension

Returns the GLWE dimension of the key.

fn polynomial_size(&self) -> PolynomialSize

Returns the polynomial size of the key.

fn input_lwe_dimension(&self) -> LweDimension

Returns the input LWE dimension of the key.

fn decomposition_base_log(&self) -> DecompositionBaseLog

Returns the number of decomposition levels of the key.

fn decomposition_level_count(&self) -> DecompositionLevelCount

Returns the logarithm of the base used in the key.

fn output_lwe_dimension(&self) -> LweDimension

Returns the output LWE dimension of the key.

impl<'a> PartialEq for LweBootstrapKeyView64<'a>

fn eq(&self, other: &LweBootstrapKeyView64<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
