Struct EvaluationError 

pub struct EvaluationError(/* private fields */);

Error produced while evaluating a Trace using the evaluate function.

Two conditions are represented using this error type:

1. An error is encountered during evaluation of the formula
2. The trace does not contain any elements.

Implementations

impl EvaluationError

pub fn wrap<E>(source: E) -> Self

where E: Error + 'static,

Create a new evaluation error for an arbitrary inner error.

The error provided this function is expected to be generated from a Formula evaluation. This function allocates on the heap.

pub fn empty() -> Self

Create a new evaluation error when a trace does not contain any elements.

Trait Implementations

impl Debug for EvaluationError

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

Formats the value using the given formatter.

impl Display for EvaluationError

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

Formats the value using the given formatter.

impl Error for EvaluationError

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>)
