Struct ExpressionError 

pub struct ExpressionError<'s> { /* private fields */ }

An error that occurs during evaluation.

Printing this error will show the error message and the location in the source code.

use somni_expr::{Context, TypeSet32};
let mut ctx = Context::<TypeSet32>::new_with_types();

let error = ctx.evaluate::<u32>("true + 1").unwrap_err();

println!("{error:?}");

// Output:
//
// Evaluation error
// ---> at line 1 column 1
//   |
// 1 | true + 1
//   | ^^^^^^^^ Failed to evaluate expression: Type error

Implementations

impl ExpressionError<'_>

pub fn into_inner(self) -> EvalError

Returns the inner EvalError.

Trait Implementations

impl<'s> Clone for ExpressionError<'s>

fn clone(&self) -> ExpressionError<'s>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionError<'_>

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

Formats the value using the given formatter.

impl<'s> PartialEq for ExpressionError<'s>

fn eq(&self, other: &ExpressionError<'s>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
