1//! A simple string-backed error type for quick error creation.

5/// A simple error type that wraps a string message.
6///
7/// Use this when you need a quick error without defining a custom error type.
8/// Works with [`ErrorReport`](crate::ErrorReport) and [`ResultExt`](crate::ResultExt).
9///
10/// # Example
11///
12/// ```rust
13/// use charon_error::StringError;
14///
15/// let err = StringError::new("something went wrong");
16/// assert_eq!(err.message, "something went wrong");
17/// ```

20    /// The error message text.
21    pub message: String,
22}

24impl StringError {
25    /// Create a new `StringError` from anything that converts to `String`.
26    #[must_use]
