chainerror

chainerror provides an error backtrace like failure without doing a real backtrace, so even after you strip your binaries, you still have the error backtrace.

chainerror has no depenendencies!

chainerror uses .source() of std::error::Error along with line()! and file()! to provide a nice debug error backtrace. It encapsulates all types, which have Display + Debug and can store the error cause internally.

Along with the ChainError<T> struct, chainerror comes with some useful helper macros to save a lot of typing.

Debug information is worth it!
