Detailed Description

template<size_t capacity_>
class seqan3::small_string< capacity_ >

Implements a small string that can be used for compile time computations.

Template Parameters

capacity_ The capacity of the small string.

This class provides a string type for small strings and compile-time contexts. It has fixed capacity, but variable size within the capacity. It is always allocated on the stack and most of it's members are constexpr-qualified. The underlying data can be exposed as a null-terminated c-style string (without copying) and conversion operators to std::string are provided (this involves copying).

Implementation notes

Internally the string stores a null-terminated array of size capacity_ + 1 and the size of the string as a member. The smallest possible type is used for storage of the size. For example, small_string<30> uses 32bytes of memory (one byte extra for the null-terminator and one byte to save the size).

Usage:

#include <seqan3/core/debug_stream.hpp>
#include <seqan3/range/container/small_string.hpp>
 
int main()
{
    constexpr seqan3::small_string sm{"hello"};     // construct from string literal at compile time!
 
    static_assert(sm[0] == 'h');                    // This way I can also test it at compile-time
 
    seqan3::debug_stream << sm.size() << '\n'; // prints 5! (the null character is only stored internally)
 
    // conversion to a normal string:
    std::string sm_string{sm.str()};
    // access data directly with a pointer to the underlying zero-terminated array:
    char const * sm_cstr{sm.c_str()};
 
    seqan3::debug_stream << sm << sm_string << sm_cstr << '\n'; // prints "hellohellohello"
}
