##### Data Members

Name | Description
--- | ---
max_size_n | Maximum size of the string excluding the null terminator.
npos | A special index.

These objects behave like `std::string` except that the storage is not dynamically allocated but rather fixed in size. These strings offer performance advantages when a protocol imposes a natural small upper limit on the size of a value.

##### Remarks

The stored string is always null-terminated.
