Trait LweBootstrapKeyConversionEngine 

pub trait LweBootstrapKeyConversionEngine<InputKey, OutputKey>: AbstractEngine
where
    InputKey: LweBootstrapKeyEntity,
    OutputKey: LweBootstrapKeyEntity,
{
    // Required methods
    fn convert_lwe_bootstrap_key(
        &mut self,
        input: &InputKey,
    ) -> Result<OutputKey, LweBootstrapKeyConversionError<Self::EngineError>>;
    unsafe fn convert_lwe_bootstrap_key_unchecked(
        &mut self,
        input: &InputKey,
    ) -> OutputKey;
}

A trait for engines converting LWE bootstrap keys.

Semantics

This pure operation generates a LWE bootstrap key containing the conversion of the input bootstrap key to a type with a different representation (for instance from cpu to gpu memory).

Formal Definition

Required Methods

fn convert_lwe_bootstrap_key( &mut self, input: &InputKey, ) -> Result<OutputKey, LweBootstrapKeyConversionError<Self::EngineError>>

Converts an LWE bootstrap key.

unsafe fn convert_lwe_bootstrap_key_unchecked( &mut self, input: &InputKey, ) -> OutputKey

Unsafely converts an LWE bootstrap key.

Safety

For the general safety concerns regarding this operation, refer to the different variants of LweBootstrapKeyConversionError. For safety concerns specific to an engine, refer to the implementer safety section.

Implementors

impl LweBootstrapKeyConversionEngine<LweBootstrapKey32, FftFourierLweBootstrapKey32> for FftEngine
