  • result

    A lightweight C++11-compatible error-handling mechanism (by bitwizeshift)

  • Example of other people trying to do it in a generic way, as a separate library (instead of in the utility part of some bigger codebase): - https://github.com/bitwizeshift/result - https://github.com/oktal/result - https://github.com/basicpp17/result17 - https://github.com/p-ranav/result

  • result

    My implementation of a C++ Result<T, E> type inspired by Rust (by oktal)

  • mamba

    The Fast Cross-Platform Package Manager (by mamba-org)

  • We started using tl::expected in https://github.com/mamba-org/mamba/ since the beginning of this year and some other related projects like https://github.com/mamba-org/powerloader . I don't know much other big open-source codebases that use that specific lib.
