Detailed Description

template<char Delimiter, typename NamedTuple>
class dfe::io_dsv_impl::NamedTupleDsvReader< Delimiter, NamedTuple >

Read records as delimiter-separated values from a text file.

The reader is strict about its input format to avoid ambiguities. If header verification is disabled, the first line will be skipped and each line must contain exactly as many columns as there are tuple members in exactly the same order. If header verification is enabled, the first line is interpreted as the header. Names in the header must match exactly to the tuple members but can be in arbitrary order. The file can contain extra columns that are not tuple members. Each following row must have exactly the same number of columns as the header.

		bool	verify_header = `true`
	)

inline

Open a file at the given path.

Parameters

path	Path to the input file
optional_columns	Record columns that can be missing in the file
verify_header	true to check header column names, false to skip

The set of optional columns must match names in the record. When allowing optional columns, header verification must be set to true.
