using base_t = char_predicate_base< char_predicate_combiner< condition_ts... > >
 The base type.
 
using data_t = constexpr_pseudo_bitset< 257 >
 Type of the data field; as soon as std::bitset is fully constexpr, use that instead!

 Combines the result of two seqan3::detail::char_predicate via logical disjunction.
 
constexpr auto operator! () const
 Return a new condition with all bits flipped.

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

predicate function to test if c satisfies the given condition.

Parameters
cThe character to be tested.
Returns
true on success, false otherwise.
