template<typename T, typename... Ts>
consteval std::size_t gtopt::detail::type_index_in() noexcept

Returns the 0-based position of T in the pack Ts..., or sizeof...(Ts) if not found. Implemented as a consteval function (C++20) with a local bool array to avoid recursive template instantiation depth.

#include <gtopt/arrow_types.hpp>
template<typename SourceArrayType>
auto gtopt::detail::widen_to_double_array(const arrow::Array& chunk) -> std::shared_ptr< arrow::DoubleArray >

#include <gtopt/arrow_types.hpp>
template<typename SourceArrayType>
auto gtopt::detail::widen_to_int32_array(const arrow::Array& chunk) -> std::shared_ptr< arrow::Int32Array >

Cast an Arrow array chunk to Int32Array, handling int8/int16/int64 conversion.

Parameters
chunk The Arrow array chunk to cast
Returns A shared pointer to an Int32Array, or nullptr if the type is incompatible
