Actions that convert a raw std::string_view token to a typed value.
Each action in this namespace transforms the pipeline value from a string representation into a specific C++ type. They are typically placed first in an action pipeline, before validation and pack actions.
Example:
| using cli::conversion::Enumeration = Choice<T, Mapper> |
| auto cli::conversion::get | ( | const NegatableResult & | r | ) | -> decltype(auto) |
| auto cli::conversion::get | ( | NegatableResult & | r | ) | -> decltype(auto) |
