ABSL Strings

This directory contains packages related to std::string operations and std::string alternatives (such as character-agnostic byte manipulation packages).

Library Listing

Two library targets are available within this directory:

• strings (//absl/strings:strings) provides classes and utility functions for manipulating and comparing strings, converting other types (such as integers) into strings, or evaluating strings for other usages (such as tokenization).

• cord (//absl/strings:cord) provides classes and utility functions for manipulating Cord elements. A Cord is a sequence of characters that internally uses a tree structure to store their data, avoiding the need for long regions of contiguous memory, and allows memory sharing, sub-std::string copy-on-write, and a host of other advanced std::string features.

Strings Library File Listing

Cord Library File Listing

The following header files are directly included within the absl::strings::cord library:

The Cord Class
