Welcome to Abseil! Abseil is an open-source collection of C++ code (compliant to C++11) designed to augment the C++ standard library. This document introduces Abseil and provides an overview of the code we’re providing.
The Abseil codebase consists of the following C++ library components:
baselibrary contains initialization code and other code which all other Abseil code depends on. Code within
basemay not depend on any other code (other than the C++ standard library).
algorithmlibrary contains additions to the C++
<algorithm>library and container-based versions of such algorithms.
containerlibrary contains additional STL-style containers.
debugginglibrary contains code useful for enabling leak checks, and stacktrace and symbolization utilities.
hashlibrary contains the hashing framework and default hash functor implementations for hashable types in Abseil.
memorylibrary contains C++11-compatible versions of
std::make_unique()and related memory management facilities.
metalibrary contains C++11-compatible versions of type checks available within C++14 and C++17 versions of the C++
numericlibrary contains C++11-compatible 128-bit integers.
stringslibrary contains a variety of strings routines and utilities, including a C++11-compatible version of the C++17
synchronizationlibrary contains concurrency primitives (Abseil’s
absl::Mutexclass, an alternative to
std::mutex) and a variety of synchronization abstractions.
timelibrary contains abstractions for computing with absolute points in time, durations of time, and formatting and parsing time within time zones.
typeslibrary contains non-container utility types, like a C++11-compatible version of
utilitylibrary contains utility and helper code.
