Functions

template<std::size_t SizeV>
constexpr auto expect(const char (&str)[SizeV]) noexcept -> fn::ExpectFixedString<SizeV, const char>

Creates a parser that expects the stream to start with the given fixed string. Parser’s expected string is fixed and cannot be changed. better performance for string literals.

template<std::size_t SizeV, typename CharT = const char>
constexpr auto expect(FixedString<SizeV, CharT> expected) noexcept -> fn::ExpectFixedString<SizeV, CharT>

Creates a parser that expects the stream to start with the given fixed string. Parser’s expected string is fixed and cannot be changed. better performance for string literals.

inline auto expect(std::string expected) noexcept -> fn::ExpectString

Creates a parser that expects the stream to start with the given string.

constexpr auto expect(char expected) noexcept -> fn::ExpectChar

Creates a parser that expects the stream to start with the given character.

constexpr auto expect_not(char expected) noexcept -> fn::ExpectChar

Creates a parser that expects the stream to start with the given character.

constexpr auto expect(Charset expected) noexcept -> fn::ExpectCharset

Creates a parser that expects the stream to start with a character the is in the given charset.

constexpr auto expect_not(Charset expected) noexcept -> fn::ExpectCharset

Creates a parser that expects the stream to start with a character the is in the given charset.
