Public Types
using	data_t = constexpr_pseudo_bitset< 257 >
	Type of the data field; as soon as std::bitset is fully constexpr, use that instead!

Public Member Functions
Logical operators
Adds logical operators to allow logical disjunction, conjunction and negation on parse conditions.
template<char_predicate rhs_t>
constexpr auto	operator\|\| (rhs_t const &) const
	Combines the result of two seqan3::detail::char_predicate via logical disjunction.

constexpr auto	operator! () const
	Return a new condition with all bits flipped.

Function call operator
template<std::integral value_t> requires (sizeof(value_t) == 1)
constexpr bool	operator() (value_t const val) const noexcept
	Invokes the condition on `val`.

template<std::integral value_t> requires (sizeof(value_t) != 1)
constexpr bool	operator() (value_t const val) const noexcept
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Output functions
std::string	message () const
	Returns the message representing this condition as std::string.

Detailed Description

template<typename derived_t>
struct seqan3::detail::char_predicate_base< derived_t >

An abstract CRTP base class for parse conditions to add logical disjunction and negation operator.

Template Parameters

derived_t The parse condition type to be extended with the logical operators. Must model seqan3::detail::char_predicate.
