Enum casper_execution_engine::shared::transform::Error

pub enum Error {
    Serialization(Error),
    TypeMismatch(StoredValueTypeMismatch),
}

Error type for applying and combining transforms. A TypeMismatch occurs when a transform cannot be applied because the types are not compatible (e.g. trying to add a number to a string). An Overflow occurs if addition between numbers would result in the value overflowing its size in memory (e.g. if a, b are i32 and a + b > i32::MAX then a AddInt32(a).apply(Value::Int32(b)) would cause an overflow).

Variants

Serialization(Error)

Error while (de)serializing data.

TypeMismatch(StoredValueTypeMismatch)

Type mismatch error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<CLValueError> for Error

fn from(cl_value_error: CLValueError) -> Error

Converts to this type from the input type.

impl From<Error> for Transform

fn from(x: Error) -> Self

Converts to this type from the input type.

impl From<TypeMismatch> for Error

fn from(error: StoredValueTypeMismatch) -> Self

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 ==.

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 TryFrom<Transform> for Error

type Error = String

The type returned in the event of a conversion error.

fn try_from(t: Transform) -> Result<Error, String>

Performs the conversion.

impl Eq for Error

impl StructuralEq for Error
