Rust Design Patterns

An open source book about design patterns and idioms in the Rust programming language that you can read here.

TODOs

Idioms

TODO stability for extensibility
TODO trait to separate visibility of methods from visibility of data (https://github.com/sfackler/rust-postgres/blob/v0.9.6/src/lib.rs#L1400)
TODO leak amplification ("Vec::drain sets the Vec's len to 0 prematurely so that mem::forgetting Drain "only" mem::forgets more stuff. instead of exposing uninitialized memory or having to update the len on every iteration")
TODO interior mutability - UnsafeCell, Cell, RefCell
TODO FFI usage (By being mindful of how to provide Rust libraries, and make use of existing libraries across the FFI, you can get more out of benefits Rust can bring)

Design patterns

TODO iterators (to safely avoid bounds checks)
TODO closures and lifetimes (coupling to lifetime)
TODO platform-specific sub-modules (https://github.com/rust-lang/rfcs/blob/master/text/0517-io-os-reform.md#platform-specific-opt-in)
TODO Module organisation (by looking at examples such as Rusts libstd, and how it integrated into the Rusts source code, lessons can be learned about ergonomic project management and API design. Closely assosciated with platform-specific sub-modules)
Entry API (Currently just a boilerplate)
TODO extension traits
TODO destructor bombs (ensure linear typing dynamically, e.g., https://github.com/Munksgaard/session-types/commit/0f25ccb7c3bc9f65fa8eaf538233e8fe344a189a)
TODO convertible to Foo trait for more generic generics (e.g., http://static.rust-lang.org/doc/master/std/fs/struct.File.html#method.open)
Late bound bounds (Currently just a boilerplate)
TODO 'shadow' borrowed version of struct - e.g., double buffering, Niko's parser generator
TODO composition of structs to please the borrow checker
TODO Error traits and Result forwarding
TODO graphs

Anti-patterns

TODO thread + catch_panic for exceptions
TODO Clone to satisfy the borrow checker
TODO Matching all fields of a struct (back compat)
TODO wildcard matches
TODO taking an enum rather than having multiple functions
TODO unwrap()ing every Result instead of forwarding it

Contributing

You are missing content in this repository that can be helpful for others and you are eager to explain it? Awesome! We are always happy about new contributions (e.g. elaboration or corrections on certain topics) to this project.

Building with mdbook

This book is built with mdbook. You can install it by running cargo install mdbook.

If you want to build it locally you can run one of these two commands in the root directory of the repository:

mdbook build

Builds static html pages as output and place them in the /book directory by default.
mdbook serve

Serves the book at http://localhost:3000 (port is changeable, take a look at the terminal output to be sure) and reloads the browser when a change occurs.
