Struct DatumConversionFailure 

pub struct DatumConversionFailure<D> {
    pub original: D,
    pub error: TypeMismatch,
}

Error type when using TryFrom/TryInto to convert a Machine::Datum into a particular type

See also types module.

Since this type contains the original Datum, it might not be Send + Sync + 'static. DatumConversionFailure also does not implement std::error::Error. You can convert this error into TypeMismatch (or extract the error field), which implements std::error::Error and is Send + Sync + 'static.

For convenience, values of this type can also be directly converted into a MachineError.

Fields

original: D

Original datum that could not be converted

error: TypeMismatch
