}Expand description
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>>
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
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
Description:
Implementation of LweBootstrapKeyConversionEngine for CoreEngine that operates on
32 bits integers. It converts a bootstrap key from the standard to the Fourier domain.
