#[non_exhaustive]
pub enum LweKeyswitchKeyGenerationError<EngineError: Error> {
NullDecompositionBaseLog,
NullDecompositionLevelCount,
DecompositionTooLarge,
Engine(EngineError),
}
Expand description
An error used with the LweKeyswitchKeyGenerationEngine
trait.
This type provides a
LweKeyswitchKeyGenerationError::perform_generic_checks
function that does error checking for the general cases, returning an Ok(())
if the inputs are valid, meaning that engine implementors would then only
need to check for their own specific errors.
Otherwise an Err(..)
with the proper error variant is returned.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
NullDecompositionBaseLog
Generic error: The key decomposition base log must be greater than zero.
NullDecompositionLevelCount
Generic error: The key decomposition level count must be greater than zero.
DecompositionTooLarge
Generic error: The decomposition precision (base log * level count) must not exceed the precision of the ciphertext.
Engine(EngineError)
Specific error to the implementing engine.
