C++ String

This is a header only C++ string implementation that supports Short String Optimisation(SSO) and Copy On Write (COW) for long string. The aim of this repository is for learning purposes that prioritises readability.

Features

  1. Short String Optimisation:
  • No allocation for sting with less than 22 (non-inclusive of \0) characters.
  1. Copy on Write:
  • Lazily copy long string (more than 256 characters) only when writer operations are invoked.
  • Utilises custom lock-free reference counting.
  1. Allow for custom allocator

Build and Testing

Build:

bazel build --cxxopt='-std=c++20' kstring

Test

bazel test --test_output=streamed kstring_test
