Enum LweCiphertextDiscardingBitExtractError 

#[non_exhaustive]
pub enum LweCiphertextDiscardingBitExtractError<EngineError: Error> {
    InputLweDimensionMismatch,
    InputKeyswitchKeyLweDimensionMismatch,
    OutputLweDimensionMismatch,
    ExtractedBitsCountMismatch,
    KeyDimensionMismatch,
    NotEnoughBitsToExtract,
    Engine(EngineError),
}

An error used with the LweCiphertextDiscardingBitExtractEngine trait.

This type provides a LweCiphertextDiscardingBitExtractError::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)

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.

InputLweDimensionMismatch

Generic error: The input ciphertext and bootstrap key LWE dimension must be the same.

InputKeyswitchKeyLweDimensionMismatch

Generic error: The input ciphertext LWE dimension must be the same as the keyswitch key input LWE dimension.

OutputLweDimensionMismatch

Generic error: The output ciphertext vector LWE dimension must be the same as the output LWE dimension of the keyswitch key.

ExtractedBitsCountMismatch

Generic error: The output LWE ciphertext vector count must be the same as the number of bits to extract.

KeyDimensionMismatch

Generic error: The keyswitch key output LWE dimension must be the same as the bootstrap key input LWE dimension.

NotEnoughBitsToExtract

Generic error: The number of bits to extract, starting from the bit at index delta_log towards the most significant bits, should not exceed the total number of available bits in the ciphertext.

Engine(EngineError)

Specific error to the implementing engine.
