+/// No such file or directory (os error 2)
+/// ```
+///
+/// # Wrapping Types That Do Not Implement `Error`
+///
+/// For example `&str` and `Box<dyn Error>`.
+///
+/// Due to restrictions for coherence `Report` cannot implement `From` for types
+/// that don't implement `Error`. Attempts to do so will give `"this type might
+/// implement Error in the future"` as an error. As such, `wrap_err()`, which
+/// uses `From` under the hood, cannot be used to wrap these types. Instead we
+/// encourage you to use the combinators provided for `Result` in `std`/`core`.
+///
+/// For example, instead of this:
+///
+/// ```rust,compile_fail
+/// use std::error::Error;
+/// use miette::{WrapErr, Report};
+///
+/// fn wrap_example(err: Result<(), Box<dyn Error + Send + Sync + 'static>>)
+/// -> Result<(), Report>
+/// {
+/// err.wrap_err("saw a downstream error")
+/// }
+/// ```
+///
+/// We encourage you to write this:
+///
+/// ```rust
+/// use miette::{miette, Report, WrapErr};
+/// use std::error::Error;
+///
+/// fn wrap_example(err: Result<(), Box<dyn Error + Send + Sync + 'static>>) -> Result<(), Report> {
+/// err.map_err(|e| miette!(e))
+/// .wrap_err("saw a downstream error")
+/// }
+/// ```
+///
+/// # Effect on Downcasting
+///
+/// After attaching a message of type `D` onto an error of type `E`, the
+/// resulting `miette::Error` may be downcast to `D` **or** to `E`.
+///
+/// That is, in codebases that rely on downcasting, `miette`'s `wrap_err()`
+/// supports both of the following use cases:
+///
+/// - **Attaching messages whose type is insignificant onto errors whose type
+/// is used in downcasts.**
+///
+/// In other error libraries whose `wrap_err()` is not designed this way, it
+/// can be risky to introduce messages to existing code because new message
+/// might break existing working downcasts. In miette, any downcast that
+/// worked before adding the message will continue to work after you add a
+/// message, so you should freely wrap errors wherever it would be helpful.
+///
+/// ```
+/// # use miette::bail;
+/// # use thiserror::Error;
+/// #
+/// # #[derive(Error, Debug)]
+/// # #[error("???")]
+/// # struct SuspiciousError;
+/// #
+/// # fn helper() -> Result<()> {
+/// # bail!(SuspiciousError);
+/// # }
+/// #
+/// use miette::{WrapErr, Result};
+///
+/// fn do_it() -> Result<()> {
+/// helper().wrap_err("Failed to complete the work")?;
+/// # const IGNORE: &str = stringify! {
+/// ...
+/// # };
+/// # unreachable!()
+/// }
+///
+/// fn main() {
+/// let err = do_it().unwrap_err();
+/// if let Some(e) = err.downcast_ref::<SuspiciousError>() {
+/// // If helper() returned SuspiciousError, this downcast will
+/// // correctly succeed even with the message in between.
+/// # return;
+/// }
+/// # panic!("expected downcast to succeed");
+/// }
+/// ```
+///
+/// - **Attaching message whose type is used in downcasts onto errors whose
+/// type is insignificant.**
+///
+/// Some codebases prefer to use machine-readable messages to categorize
+/// lower level errors in a way that will be actionable to higher levels of
+/// the application.
+///
+/// ```
+/// # use miette::bail;
+/// # use thiserror::Error;
+/// #
+/// # #[derive(Error, Debug)]
+/// # #[error("???")]
+/// # struct HelperFailed;
+/// #

+/// // HelperFailed is the message that has been attached to
+/// // that error.
+/// # return;
+/// }
