Visual Guide to Rust's Core Type System and Lang Items

By

Summary

A visual guide to the Rust type system, focusing on lang_items — types and traits built into the language to support specific syntax. The guide explains that types like Vec, String, and HashMap are not included because they are just structs built from library code, not core language items. The purpose is to demystify what can be built purely in library code versus what is built into the language itself.
