-/// Iterator of a chain of source errors.

-/// This type is the iterator returned by [`Report::chain`].

-/// # Example
-///
-/// ```
-/// use miette::Report;
-/// use std::io;
-///
-/// pub fn underlying_io_error_kind(error: &Report) -> Option<io::ErrorKind> {
-///     for cause in error.chain() {
-///         if let Some(io_error) = cause.downcast_ref::<io::Error>() {
-///             return Some(io_error.kind());
-///         }
-///     }
-///     None
