toml_fwd.hpp #

toml_fwd.hpp contains forward declarations of structures defined in toml11 and macro definitions.

When only forward declarations of toml11 structures are needed and implementation is not required, including toml_fwd.hpp instead of toml.hpp can reduce compilation time.

Since this file only contains forward declarations, you cannot use toml::table, defined as toml::basic_value<toml::type_config>::table_type, and similarly defined toml::array. This is because they require the implementation of basic_value.

This header file and toml.hpp are located under ${TOML11_INCLUDE_DIR}/, while other header files are located under ${TOML11_INCLUDE_DIR}/toml11/.
