Namespaces
	csv
	The all encompassing namespace.
	csv::internals
	Stuff that is generally not of interest to end-users.

Macros
#define	CSV_INLINE
	Helper macro which should be #defined as "inline" in the single header version.
#define	STATIC_ASSERT(x)   static_assert(x, "Assertion failed")
#define	IF_CONSTEXPR   if
	Expands to if constexpr in C++17 and if otherwise.
#define	CONSTEXPR_VALUE   const
	Expands to constexpr in C++17 and const otherwise. More...
#define	CONSTEXPR_17   inline
#define	CONSTEXPR_14   inline
#define	CONSTEXPR_VALUE_14   const
#define	CONSTEXPR   inline
	Expands to constexpr in decent compilers and inline otherwise. More...

Typedefs
using	csv::string_view = nonstd::string_view
	The string_view class used by this library.
template<bool B, class T = void>
using	csv::enable_if_t = typename std::enable_if< B, T >::type
using	csv::internals::ParseFlagMap = std::array< ParseFlags, 256 >
	An array which maps ASCII chars to a parsing flag.
using	csv::internals::WhitespaceMap = std::array< bool, 256 >
	An array which maps ASCII chars to a flag indicating if it is whitespace.

Enumerations
enum class	csv::internals::ParseFlags {   csv::internals::QUOTE_ESCAPE_QUOTE = 0 , csv::internals::QUOTE = 2 | 1 , csv::internals::NOT_SPECIAL = 4 , csv::internals::DELIMITER = 4 | 2 ,   csv::internals::NEWLINE = 4 | 2 | 1 }
	An enum used for describing the significance of each character with respect to CSV parsing. More...

Functions
template<typename T >
bool	csv::internals::is_equal (T a, T b, T epsilon=0.001)
constexpr ParseFlags	csv::internals::quote_escape_flag (ParseFlags flag, bool quote_escape) noexcept
	Transform the ParseFlags given the context of whether or not the current field is quote escaped.
	csv::internals::STATIC_ASSERT (ParseFlags::DELIMITER< ParseFlags::NEWLINE)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::NOT_SPECIAL, false)==ParseFlags::NOT_SPECIAL)
	Optimizations for reducing branching in parsing loop. More...
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::QUOTE, false)==ParseFlags::QUOTE)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::DELIMITER, false)==ParseFlags::DELIMITER)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::NEWLINE, false)==ParseFlags::NEWLINE)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::NOT_SPECIAL, true)==ParseFlags::NOT_SPECIAL)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::QUOTE, true)==ParseFlags::QUOTE_ESCAPE_QUOTE)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::DELIMITER, true)==ParseFlags::NOT_SPECIAL)
	csv::internals::STATIC_ASSERT (quote_escape_flag(ParseFlags::NEWLINE, true)==ParseFlags::NOT_SPECIAL)

Variables
const int	csv::internals::PAGE_SIZE = 4096
	Size of a memory page in bytes. More...
constexpr size_t	csv::internals::ITERATION_CHUNK_SIZE = 10000000
	For functions that lazy load a large CSV, this determines how many bytes are read at a time.
constexpr int	csv::CSV_NOT_FOUND = -1
	Integer indicating a requested column wasn't found.

Macro Definition Documentation

CONSTEXPR

#define CONSTEXPR   inline

Expands to constexpr in decent compilers and inline otherwise.

Intended for functions and methods.

Definition at line 117 of file common.hpp.

CONSTEXPR_VALUE

#define CONSTEXPR_VALUE   const

Expands to constexpr in C++17 and const otherwise.

Mainly used for global variables.

Definition at line 85 of file common.hpp.
