# Rust Ownership and Borrowing

Ownership rules, borrowing, slices, and lifetimes.

For ownership rules, borrowing patterns, slices, and lifetime annotations, see `references/ownership.md`.

## Anti-fabrication

This skill follows `core:anti-fabrication`. Every claim about ownership, borrowing, and
lifetime rules is verified against the official Rust Book chapters cited in `sources.md` —
not inferred from generic familiarity with the language. Before asserting borrow-checker
behavior this skill and its references do not cover, check the installed Rust toolchain's
documentation rather than guessing.
