Detailed Description

template<int char_v>
struct seqan3::detail::is_char_type< char_v >

Parse condition that checks if a given value is equal to char_v.

Template Parameters
char_vnon-type template parameter with the value that should be checked against.

Member Function Documentation

◆ operator()()

bool operator() ( char_type  c)
inherited

predicate function to test if c satisfies the given condition.

Parameters
cThe character to be tested.
Returns
true on success, false otherwise.
Attention
This is a concept requirement, not an actual function (however types satisfying this concept will provide an implementation).
