6/// Convenience response to create an error response from a non-[`IntoResponse`] error
7///
8/// This provides a method to quickly respond with an error that does not implement
9/// the `IntoResponse` trait itself. This type should only be used for debugging purposes or internal
10/// facing applications, as it includes the full error chain with descriptions,
11/// thus leaking information that could possibly be sensitive.
12///
13/// ```rust
14/// use axum_extra::response::InternalServerError;
15/// use axum_core::response::IntoResponse;
16/// # use std::io::{Error, ErrorKind};
17/// # fn try_thing() -> Result<(), Error> {
18/// #   Err(Error::new(ErrorKind::Other, "error"))
19/// # }
20///
21/// async fn maybe_error() -> Result<String, InternalServerError<Error>> {
22///     try_thing().map_err(InternalServerError)?;
23///     // do something on success
24///     # Ok(String::from("ok"))
25/// }
26/// ```
