A single-header C++14 dependency injection library with no external dependencies, part of the Boost.Ext ecosystem. It provides an injector-based API for binding interfaces to implementations and constructing object graphs at compile time.

Use cases

• dependency injection in C++ projects
• bind interfaces to implementations in C++
• create object graphs without manual wiring
• make C++ code easier to unit test with loosely coupled design
• header-only DI framework with no dependencies
• reduce boilerplate constructor wiring in C++

When to choose

• you want a lightweight, header-only DI solution in C++14 or later
• you need zero runtime overhead and minimal binary size
• you want to decouple classes for better testability
• you prefer compile-time object graph construction

When to avoid

• your project targets a C++ standard below C++14
• you need runtime-configurable dependency injection
• you prefer a full framework with extensive module system
• you require a formally licensed Boost library (it's Boost.Ext, not official Boost)
