Package-level declarations

HTTP status codes recognised by libtorrent, ported from errors::http_errors (include/libtorrent/error_code.hpp) and the http_error_category message formatter in src/error_code.cpp.

libtorrent's primary error enumeration, ported from errors::error_code_enum (include/libtorrent/error_code.hpp) together with the human-readable strings from libtorrent_error_category::message() (src/error_code.cpp).

Thrown when a libtorrent operation fails with a LibtorrentError. Mirrors the way libtorrent surfaces a libtorrent_category() error_code as a system_error / libtorrent_exception; the exception message is the error's human-readable LibtorrentError.message.
