Crate other_error

Expand description

§other-error

Lightweight no-std compatible wrapper types for sharing (via Arc or Rc) and combining errors.

§Usage

use other_error::{ArcError, EitherError};
use either::Either;

// Make a non-Clone error cheaply cloneable and shareable.
let err = ArcError::new(std::io::Error::other("boom"));
let also_err = err.clone(); // shares the same allocation

// Represent a value that may fail in one of two ways.
let either: EitherError<std::io::Error, std::fmt::Error> =
    Either::Left(std::io::Error::other("boom")).into();
println!("{either}");

§MSRV

The minimum supported rust version is 1.81, which can be changed in the future. There is no guarantee that this library will work on older versions of rust.
