What's here
Every public item in the Rust standard library — 2,028 structs, enums, traits, functions, macros, constants, and primitives — gets its own page. Each page includes a plain-English explanation of what the item does, when to reach for it, two annotated code examples, common pitfalls, performance notes, and links to related items in the same module.
Beyond the per-item reference, RustDocs Hub offers long-form guides for the most important modules — collections, iter, io, fs, sync, thread, option, result, fmt, str, mem, ptr, cell, env, time, process, path, net, error, marker, num, cmp, slice, pin, future, task, panic, convert, default — covering the design tradeoffs you actually care about when picking between similar types.
Where the data comes from
The reference index is seeded from the official Rust standard library documentation at doc.rust-lang.org/std/all.html. Every link points back to the canonical source. The annotated prose, examples, and pitfalls are written by hand.
