+ <longdescription>
+ The Rust Standard Library is the foundation of portable Rust software,
+ a set of minimal and battle-tested shared abstractions for the broader Rust ecosystem.
+ It offers core types, like Vec&lt;T&gt; and Option&lt;T&gt;, library-defined operations on language primitives,
+ standard macros, I/O and multithreading, among many other things.
