struct	seqan3::detail::char_predicate_negator< condition_t >
	Logical not operator for a parse condition. More...
class	seqan3::detail::constexpr_pseudo_bitset< N >
	A data structure that implements a subset of std::bitset as constexpr. More...
class	seqan3::detail::fast_istreambuf_iterator< char_t, traits_t >
	Functionally the same as std::istreambuf_iterator, but faster. More...
class	seqan3::detail::fast_ostreambuf_iterator< char_t, traits_t >

	Concept for output streams. More...
struct	seqan3::detail::stream_buffer_exposer< char_t, traits_t >
	Functionally the same as std::basic_streambuf<char_t, traits_t_>, but exposes protected members as public. More...

Enumerations
enum	seqan3::fmtflags2 { seqan3::none = 0 , seqan3::utf8 = 1 , seqan3::small_int_as_number = 1 << 1 , default_ = small_int_as_number }
	Flags that change the behaviour of the seqan3::debug_stream. More...

Variables
template<char op, typename condition_head_t , typename ... condition_ts>
const std::string	condition_message_v
	Defines a compound std::string consisting of all given conditions separated by the operator-name op. More...

	A global instance of seqan3::debug_stream_type.

Detailed Description

The stream sub-module contains data structures and functions for streaming and tokenization.

Enumeration Type Documentation

fmtflags2

enum seqan3::fmtflags2

Flags that change the behaviour of the seqan3::debug_stream.

See also

seqan3::enum_bitwise_operators enables combining enum values.

Enumerator
none	No flag is set.
utf8	Enables use of non-ASCII UTF8 characters in formatted output.
small_int_as_number	int8_t and uint8_t are often aliases for signed char and unsigned char resp. resulting in chars being printed; this options prints them as numbers.

Variable Documentation

condition_message_v

template<char op, typename condition_head_t , typename ... condition_ts>

const std::string condition_message_v

related

Initial value:

{
    std::string{"("} +
    (condition_head_t::msg + ... +
        (std::string{" "} + std::string{{op, op}} + std::string{" "} + condition_ts::msg)) +
    std::string{")"}
}

Defines a compound std::string consisting of all given conditions separated by the operator-name op.

Template Parameters

op	non-type template parameter specifying the separator character, e.g. '|'.
condition_head_t	The first condition type in the message. Ensures that there is at least one type.
condition_ts	Remaining list of conditions separated by op.
