Represents an error that can occur in this crate.

Variants

IRError(Error)

An issue with an FheProgram.

SealError(Error)

An error occurred in the SEAL library.

MissingRelinearizationKeys

Tried to run an Fhe Program that requires relinearization keys, but didn’t provide any.

MissingGaloisKeys

Tried to run an Fhe Program that requires Galois keys, but didn’t provide any.

IncorrectCiphertextCount

Returned when:

• The wrong number of ciphertexts were provided as parameters to an Fhe Program.
• The wrong number of ciphertexts were returned from an Fhe Program.

ParameterMismatch

An argument is incompatible with the parameters in the runtime.

ArgumentMismatch

Fields

expected: Vec<Type, Global>

The arguments in the call signature of the FHE program.

actual: Vec<Type, Global>

The given arguments.

The given arguments do not match the call signature of the FHE program.

ReturnMismatch

Fields

expected: Vec<Type, Global>

The return types in the call signature of the FHE program.

actual: Vec<Type, Global>

The given return types.

The given return types do not match the FHE program interface.

TypeMismatch

Fields

expected: Type

The expected type.

actual: Type

The actual type.

The given type does not match the expected.

ReturnTypeMetadataError

The vector indicating the number of ciphertexts in the return types isn’t the same length as the signature’s return type. Running valid FHE programs created by the Sunscreen compiler should never produce this error.

TooMuchNoise

Decryption failed because the cipher text had too much noise.

FheProgramRunError(FheProgramRunFailure)

Executing an Fhe Program failed.

FheTypeError(String)

This variant wraps some error specific to the representation of FheTypes. For example, a type encoding even numbers would return this if you pass an odd number.

ParamDeserializationError

Failed to deserialize bytes as a Params object.

NoPlaintextData

The given Plaintext had no data.

MalformedPlaintext

The given Plaintext had an incorrect array count.

BincodeError(String)

An error occurred when serializing/deserializing with bincode.

NotASealPlaintext

Called inner_as_seal_plaintext on non-Seal plaintext.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl From<Box<ErrorKind, Global>> for Error

fn from(err: Box<ErrorKind, Global>) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: RuntimeError) -> Self

Converts to this type from the input type.

impl From<FheProgramRunFailure> for Error

fn from(err: FheProgramRunFailure) -> Error

Converts to this type from the input type.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Error
