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) and [std::fmt::Debug], making it easy to display.
