## What it is
Fruit is a dependency injection framework for C++, loosely inspired by Java's Guice. It uses C++11 metaprogramming to catch most injection errors at compile time and organizes code into composable components from which injectors create instances.

## Use cases
- dependency injection in C++ projects
- bind interfaces to implementations at compile time
- split C++ code into composable modules/components
- catch missing bindings and dependency loops before runtime
- assisted injection and factory auto-registration in C++
- low-overhead DI for performance-sensitive C++ applications

## When to choose
- you want Guice-style DI in C++ with errors caught at compile time
- you need modular component assembly with minimal runtime overhead
- you want a mature, Google-backed DI framework with cross-platform CI

## When to avoid
- your project targets pre-C++11 compilers
- you prefer runtime-configured DI or reflection-based containers
- you need DI for languages other than C++

## Facets
- artifact type: framework
- maturity: stable
- function: developer-tools, middleware
- domain: developer-tools, cross-platform
- platform: cpp, windows, cross-platform
- tags: dependency-injection, compile-time-checks, guice-inspired, cpp11, metaprogramming, linux, macos
