Fix failing test due to invalid_runtime_symbol_definitions https://github.com/rust-lang/rust/pull/158522 added a new deny-by-default lint that rejects code that has the wrong definition for well-known functions like malloc. However, this test is explicitly trying to illustrate that, so it needs to reduce the lint level.
This book explains the concept of “editions”, major new eras in Rust's development. You can read the book online.
The Rust Edition Guide is dual licensed under MIT/Apache2, just like Rust itself. See the LICENSE-* files in this repository for more details.
You can also build the book and read it locally if you'd like.
Building the book requires mdBook 0.5. To get it:
$ cargo install mdbook@^0.5
The most straight-forward way to build and view the book locally is to use the following command:
$ mdbook serve --open
This builds the HTML version of the book, starts a webserver at http://localhost:3000, and opens your default web browser. It will also automatically rebuild the book whenever the source changes, and the page should automatically reload.
To run the tests:
$ mdbook test
