error-code

Alternative Error for Rust.

It's goal is to be able to provide simplified Error which would work in no_std environment

Requirements

• alloc - Crate uses allocator to create dynamic message, when necessary (Only System category uses heap on Windows).

Features

• std - enables std::error::Error implementation
• ufmt - enables ufmt formatting implementation

Categories

Library introduces the concept of categories, similar to that of C++ std::error_category. Each category can be used to describe set of integral error codes.

Following implementations are builtin:

• Posix - POSIX category. To access integer constants use libc
• System - System category. To access integer constants use libc on unix, and winapi on Windows
• Plain - Plain errors without any category.
