I thought a static_string is a type that owns the string data, so
nothing like a string_view (mutable or not) at all.

The difference compared to a std::string would be the same as
the difference between std::array vs std::vector i.e. the data is
stored in a fixed buffer inside the type and not on the heap,
which in turn means there is a fixed capacity (configurable via
a template parameter).

Thats exactly what I see in https://github.com/boostorg/beast/blob/b7230f12f16fe7a9f7a1ece5be1f607c8552448a/include/boost/beast/core/static_string.hpp

so I'm not sure, where your comparison to string_view comes
from.
