Introduction

If you are familiar with Java's generics, and are coming to Rust, you might be lead to assume that its generics are working the same way.

However, due to the different type systems, and different implementation details, there are quite a few differences between generic code in both languages.

This document tries to give a short summary about those differences:

env = Environment(
    CCFLAGS = ['-Wall', '-Werror'],
)
env.Program('mkdir_p_test', ['mkdir_p.c', 'test.c'])

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

    sieve[0] = sieve[1] = false;
    for (size_t i = 2; i < N; i++) sieve[i] = true;
    for (size_t i = 2; i < N; i++) {
      if (sieve[i])
        for (size_t j = i*i; j < N; j += i) sieve[j] = false;

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

Tip

Have a look at git-conventional-commits , a CLI util to ensure these conventions and generate verion and changelogs

/**
 * Defines deep recursive function that keeps its stack on the heap,
 * which allows very deep recursive computations that do not use the actual call stack.
 * To initiate a call to this deep recursive function use its [invoke] function.
 * As a rule of thumb, it should be used if recursion goes deeper than a thousand calls.
 *
 * The [DeepRecursiveFunction] takes one parameter of type [T] and returns a result of type [R].
