Enum OracleError

pub enum OracleError {
    MemoryAccess(Addr),
    InstructionFetchMemoryAccess(Addr),
    InvalidInstruction,
    GeneralFault,
    Unreliable,
    ComputationError,
    Timeout,
    MultipleInstructionsExecuted,
    ApiError(String),
}

Error returned when an error occurs in an Oracle during instruction observation.

Variants

MemoryAccess(Addr)

Represents any page fault. Might be an instruction fetch or data fetch.

InstructionFetchMemoryAccess(Addr)

A memory access that occurred while trying to fetch the next instruction. This is an optimization that is returned if possible by the oracle. The oracle may fall back to returning a MemoryAccess error instead, if it is not possible to distinguish between instruction fetches and normal data fetches.

InvalidInstruction

The undefined instruction fault was raised.

GeneralFault

A general fault was raised.

Unreliable

The intruction execution produces different results when executed multiple times.

ComputationError

A computation error fault or exception was raised. For example: dividing by zero.

Timeout

Observation timeout occurred.

MultipleInstructionsExecuted

Instruction execution did not halt after executing a single instruction. This makes it impossible to observe the instruction execution.

ApiError(String)

An API error occurred.

Implementations

impl OracleError

pub fn api<E: Error + Send + Sync + 'static>(e: E) -> Self

Creates an API error.

Trait Implementations

impl Clone for OracleError

fn clone(&self) -> OracleError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OracleError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OracleError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OracleError

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

Formats the value using the given formatter.

impl Error for OracleError

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 JsonSchema for OracleError

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Serialize for OracleError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
