//! A `libstd` wrapper with more detailed errors. This crate mirrors the `std`
//! module tree, replacing failable functions and structs with wrappers that add
//! additional information to the errors returned. *WIP, so not all of `libstd`
//! may be covered*.
//!
//! To use `ex`, simply replace a `use std::x` with `use ex::x` for any `x`.
//! Some structs are different from `libstd`'s, so there might exist some
//! friction with external crates. In that case, see the `Wrapper` trait on how
//! to get the wrapped structs.
//!
//! `ex` also uses custom error types to transport the augmented error messages.
//! In all cases, you can use `err.cause()` to get a reference to the original
//! error, or the `Wrapper` trait.
