Why Adopt Abseil?

Or: Why the world has room for another collection of C++ utility libraries

There are a few main reasons we recommend Abseil as your first choice for utility code when starting a new C++ project:

Compatibility with current and future C++ standards, and planned evolution over time

Compatibility with Google OSS projects - these are the foundational types for things like Protocol Buffers, gRPC, and TensorFlow

Upgrade Support - make it easy to live at head

Production Experience - These are the interfaces that we are using in Google production

Interest in a different set of design priorities than the C++ standard

CodemapThe Abseil codebase consists of the following C++ library components:

base Abseil Fundamentals

The base library contains initialization code and other code which all other Abseil code depends on. Code within base may not depend on any other code (other than the C++ standard library).

algorithm

The algorithm library contains additions to the C++ <algorithm> library and container-based versions of such algorithms.

container

The container library contains additional STL-style containers.

debugging

The debugging library contains code useful for enabling leak checks. Future updates will add stacktrace and symbolization utilities.

memory

The memory library contains C++11-compatible versions of std::make_unique() and related memory management facilities.

CodemapThe Abseil codebase consists of the following C++ library components:

meta

The meta library contains C++11-compatible versions of type checks available within C++14 and C++17 versions of the C++ <type_traits> library.

numeric

The numeric library contains C++11-compatible 128-bit integers.

strings

The strings library contains a variety of strings routines and utilities, including a C++11-compatible version of the C++17 std::string_view type.

synchronization

The synchronization library contains concurrency primitives (Abseil’s absl::Mutex class, an alternative to std::mutex) and a variety of synchronization abstractions.

time

The time library contains abstractions for computing with absolute points in time, durations of time, and formatting and parsingtime within time zones.

types

The types library contains non-container utility types, like a C++11-compatible version of absl::optional.
