err-report

Clone of the unstable std::error::Report type.

Backtrace support is omitted due to nightly requirement.

Examples

use std::ffi::CString;

use err_report::Report;

let invalid_utf8 = [b'f', 0xff, b'o', b'o'];
let c_string = CString::new(invalid_utf8).unwrap();
let err = c_string.into_string().unwrap_err();

// without Report, the source/root error is not printed
assert_eq!("C string contained non-utf8 bytes", err.to_string());

// with Report, all details in error chain are printed
assert_eq!(
    "C string contained non-utf8 bytes: invalid utf-8 sequence of 1 bytes from index 1",
    Report::new(err).to_string(),
);
