//! # periodic-elements
//! This crate provides a list of all 118 discovered elements, as well as additional information
//! about each. You'll probably want to use the constant [`ELEMENTS`], as it provides a `'static`
//! slice of elements. Additionally, this crate uses [std::borrow::Cow] extensively, as it allows
//! for mutating element information very efficiently, while not requiring heap allocations by
//! default. Additionally, every field within [`Element`] supports [`std::fmt::Display`]
//! (with the exception of [`cpk`](Element::cpk)) and [`std::fmt::Debug`], making it easy to display.
