Struct FormulaError 

pub struct FormulaError { /* private fields */ }

The error type when evaluating a state trace using a Predicate.

Implementations

impl FormulaError

pub fn new(time: f64, error: EvaluationError) -> Self

Create a new evaluation error for a given time.

Example

use banquo::predicate::{EvaluationError, FormulaError};

let err = FormulaError::new(1.0, EvaluationError::missing("x"));

pub fn time(&self) -> f64

Returns the time of the state that produced the EvaluationError.

pub fn error(&self) -> &EvaluationError

Returns a reference to the EvaluationError that was generated.

Trait Implementations

impl Clone for FormulaError

fn clone(&self) -> FormulaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormulaError

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

Formats the value using the given formatter.

impl Display for FormulaError

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

Formats the value using the given formatter.

impl Error for FormulaError

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>)

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

Provides type-based access to context intended for error reports.
