Detailed Description

template<std::size_t N>
struct comms::FixedString< N >

Compile-time fixed-size string usable as a non-type template parameter.

Construct via CTAD from a string literal:

FixedString id{"order.created"};   // N = 14 (includes null terminator)

The class is a structural type so it can appear directly in template argument lists, e.g. Event<"order.created">.

FixedString()

template<std::size_t N>

constexpr comms::FixedString< N >::FixedString ( )

Default-constructs an all-‘’\0'string.

Present so the type stays default-constructible — required by nlohmann/json'sfrom_jsonpath (seecommons/json.hpp`).
