This is a cosmetic change that aims to make test failures clearer. Human readers no longer need to do as much mental math to deduce the magnitude of the failure. It does not change the semantics of the test assertions. PiperOrigin-RevId: 231644805 GitOrigin-RevId: 2c12ae8d6cbb8cbeb3ff446393578dd0d6d0cf8c Change-Id: Ic121a26a7a6bb7441da6a8c1d7797bee4f705fdc |

Abseil - C++ Common Libraries
The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++11) designed to augment the C++ standard library.

About Abseil
Abseil is an open-source collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's own C++ code base, has been extensively tested and used in production, and is the same code we depend on in our daily coding lives.
In some cases, Abseil provides pieces missing from the C++ standard; in others, Abseil provides alternatives to the standard for special needs we've found through usage in the Google code base. We denote those cases clearly within the library code we provide you.
Abseil is not meant to be a competitor to the standard library; we've just found that many of these utilities serve a purpose within our code base, and we now want to provide those resources to the C++ community as a whole.
Quickstart
If you want to just get started, make sure you at least run through the Abseil Quickstart. The Quickstart contains information about setting up your development environment, downloading the Abseil code, running tests, and getting a simple binary working.
Building Abseil
Bazel is the official build system for Abseil, which is supported on most major platforms (Linux, Windows, MacOS, for example) and compilers. See the quickstart for more information on building Abseil using the Bazel build system.
If you require CMake support, please check the CMake build instructions.
Codemap
Abseil contains the following C++ library components:
base
Abseil Fundamentals
Thebase
library contains initialization code and other code which all other Abseil code depends on. Code withinbase
may not depend on any other code (other than the C++ standard library).algorithm
Thealgorithm
library contains additions to the C++<algorithm>
library and container-based versions of such algorithms.container
Thecontainer
library contains additional STL-style containers, including Abseil's unordered "Swiss table" containers.debugging
Thedebugging
library contains code useful for enabling leak checks, and stacktrace and symbolization utilities.hash
Thehash
library contains the hashing framework and default hash functor implementations for hashable types in Abseil.memory
Thememory
library contains C++11-compatible versions ofstd::make_unique()
and related memory management facilities.meta
Themeta
library contains C++11-compatible versions of type checks available within C++14 and C++17 versions of the C++<type_traits>
library.numeric
Thenumeric
library contains C++11-compatible 128-bit integers.strings
Thestrings
library contains a variety of strings routines and utilities, including a C++11-compatible version of the C++17std::string_view
type.synchronization
Thesynchronization
library contains concurrency primitives (Abseil'sabsl::Mutex
class, an alternative tostd::mutex
) and a variety of synchronization abstractions.time
Thetime
library contains abstractions for computing with absolute points in time, durations of time, and formatting and parsing time within time zones.types
Thetypes
library contains non-container utility types, like a C++11-compatible version of the C++17std::optional
type.utility
Theutility
library contains utility and helper code.
