ftl

codecov Build Status CMake

Overview

FTL is a C++17-based library that provides a more convenient API for collections processing. The API is heavily inspired by the Rust programming language.

Basic usage

Collection processing with FTL is very easy. Below you can find a simple example presenting the power of the FTL.

struct Tree { 
    enum Kind { Oak, Acer, Pine, Other };
    int height;
    int diameter;
    Kind kind;
    int volume() const;
};

ftl::vector<Tree> cityTrees{...};
int oakVolSum = 0;

// Old-school style
for (const auto& tree: cityTrees) {
  if (tree.kind == Tree::Oak) {
    if (tree.diameter > 25) 
        oakVolSum += tree.volume();
  }
}

// FTL style
const auto totalVolume = cityTrees.iter()
               .filter([](const auto &tree) { return tree.kind == Tree::Oak && tree.diameter > 25; })
               .map([](const auto &tree) { return tree.volume(); })
               .sum();
