Derive Rust Errors

This crate uses macros 1.1 to derive custom errors.

Getting Started

Add this crate to your dependencies section:-

[dependencies]
derive-error = "0.0.0"

Import it in your main.rs or lib.rs:-

#[macro_use]
extern crate derive-error;

Deriving errors is simple. Here is an example:

#[derive(Error)]
pub enum Error {
  Io(::std::io::Error),
}

That's it!
