Enum casper_execution_engine::shared::transform::Error

#[non_exhaustive]
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 (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.

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, 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 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 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

impl StructuralPartialEq for Error
