exn provides the missing context APIs for core::error::Error.
It organizes errors as a tree structure, allowing you to easily access the root cause and all related errors with their context.

This crate is no_std compatible, while the alloc crate is still required for heap allocations.
It is worth noting that no_std support is a nice-to-have feature, and can be dropped if it blocks other important features in the future. Before 1.0, once exn APIs settle down, the decision on whether to keep no_std as a promise will be finalized.
