Enum LweCiphertextDiscardingExtractionError 

#[non_exhaustive]
pub enum LweCiphertextDiscardingExtractionError<EngineError: Error> {
    SizeMismatch,
    MonomialIndexTooLarge,
    Engine(EngineError),
}

An error used with the LweCiphertextDiscardingExtractionEngine trait.

This type provides a LweCiphertextDiscardingExtractionError::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.

SizeMismatch

Generic error: The sizes of the output LWE (LWE dimension) and the input GLWE (GLWE dimension * poly size) must be compatible.

MonomialIndexTooLarge

Generic error: The monomial index must be smaller than the GLWE polynomial size.

Engine(EngineError)

Specific error to the implementing engine.

Implementations

impl<EngineError: Error> LweCiphertextDiscardingExtractionError<EngineError>

pub fn perform_generic_checks<GlweCiphertext, LweCiphertext>( output: &LweCiphertext, input: &GlweCiphertext, nth: MonomialIndex, ) -> Result<(), Self>

where GlweCiphertext: GlweCiphertextEntity, LweCiphertext: LweCiphertextEntity,

Validates the inputs

Trait Implementations

impl<EngineError: Clone + Error> Clone for LweCiphertextDiscardingExtractionError<EngineError>

fn clone(&self) -> LweCiphertextDiscardingExtractionError<EngineError>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<EngineError: Debug + Error> Debug for LweCiphertextDiscardingExtractionError<EngineError>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<EngineError: Error> Display for LweCiphertextDiscardingExtractionError<EngineError>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<EngineError: Error> Error for LweCiphertextDiscardingExtractionError<EngineError>

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<EngineError: PartialEq + Error> PartialEq for LweCiphertextDiscardingExtractionError<EngineError>

fn eq( &self, other: &LweCiphertextDiscardingExtractionError<EngineError>, ) -> 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.
