Enum wagon_value::ValueError

pub enum ValueError<T: Valueable> {
    Fatal(String),
    OperationError(T, T, String),
    FloatIsNan(FloatIsNan),
    IntConversionError(TryFromIntError),
    NegationError(T),
    ComparisonError(T, T),
    ConversionError(T),
}

Errors that can occur while dealing with semi-dynamic Values.

A ValueError<Value<T>> can be automatically converted into a ValueError<T> when you are implementing your own Valueable type, but the compiler may require some manual convincing to get it to work (as in, you will have to call from manually).

Variants

Fatal(String)

Something horrible happened for which we have no specific error.

OperationError(T, T, String)

Tried to perform some operation on two incompatible values.

FloatIsNan(FloatIsNan)

Tried to perform an operation on a float which is NaN.

IntConversionError(TryFromIntError)

Tried to convert something from an int and failed.

NegationError(T)

This type can not be negated.

ComparisonError(T, T)

Tried to compare a value to another value and failed.

ConversionError(T)

Tried to convert T to Value but failed

Trait Implementations

impl<T: Clone + Valueable> Clone for ValueError<T>

fn clone(&self) -> ValueError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Valueable> Debug for ValueError<T>

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

Formats the value using the given formatter.

impl<T: Valueable> Display for ValueError<T>

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

Formats the value using the given formatter.

impl<T: Valueable> Error for ValueError<T>

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<T: Valueable> From<FloatIsNan> for ValueError<T>

fn from(value: FloatIsNan) -> Self

Converts to this type from the input type.

impl<T: Valueable> From<Infallible> for ValueError<T>

fn from(e: Infallible) -> Self

Converts to this type from the input type.

impl<T: Valueable> From<TryFromIntError> for ValueError<T>

fn from(value: TryFromIntError) -> Self

Converts to this type from the input type.

impl<T: Valueable + From<Value<T>>> From<ValueError<Value<T>>> for ValueError<T>

fn from(value: ValueError<Value<T>>) -> Self

Converts to this type from the input type.

impl<T: PartialEq + Valueable> PartialEq for ValueError<T>

fn eq(&self, other: &ValueError<T>) -> 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.
