Abseil - C++ Common Libraries

The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++14) designed to augment the C++ standard library.

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.

Codemap

Abseil contains the following C++ library components:

• base
  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.
• cleanup
  The cleanup library contains the control-flow-construct-like type absl::Cleanup which is used for executing a callback on scope exit.
• container
  The container library contains additional STL-style containers, including Abseil’s unordered “Swiss table” containers.
• crc The crc library contains code for computing error-detecting cyclic redundancy checks on data.
• debugging
  The debugging library contains code useful for enabling leak checks, and stacktrace and symbolization utilities.
• flags
  The flags library contains code for handling command line flags for libraries and binaries built with Abseil.
• hash
  The hash library contains the hashing framework and default hash functor implementations for hashable types in Abseil.
• log
  The log library contains LOG and CHECK macros and facilities for writing logged messages out to disk, stderr, or user-extensible destinations.
• memory
  The memory library contains memory management facilities that augment C++’s <memory> library.
• meta
  The meta library contains compatible versions of type checks available within C++14 and C++17 versions of the C++ <type_traits> library.
• numeric
  The numeric library contains 128-bit integer types as well as implementations of C++20’s bitwise math functions.
• profiling
  The profiling library contains utility code for profiling C++ entities. It is currently a private dependency of other Abseil libraries.
• random
  The random library contains functions for generating psuedorandom values.
• status
  The status library contains abstractions for error handling, specifically absl::Status and absl::StatusOr<T>.
• strings
  The strings library contains a variety of strings routines and utilities, including a C++14-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 parsing time within time zones.
• types
  The types library contains non-container utility types, like a C++14-compatible version of the C++17 std::optional type.
• utility
  The utility library contains utility and helper code.
