compare(const CharT* s) constructed a temporary basic_static_cstring<N>
from s and delegated to the class-type overload. The constructor throws
std::length_error when traits::length(s) > N, and because compare() is
noexcept, the throw led to std::terminate():
static_cstring<3> s("abc");
s.compare("abcd"); // terminate() via noexcept throw
The free operator==() / operator!=() overloads for const CharT*, which
delegate to compare(), had the same flaw.
This directory contains an experimental implementation of basic_static_cstring, which differs from basic_static_string in the following ways:
basic_static_cstring |
basic_static_string |
|
|---|---|---|
| Layout | sizeof == N + 1 |
Has size member |
| Embedded NULs | Not supported | Supported |
| Trivially copyable | Yes | No |
Additionally, when N <= UCHAR_MAX, basic_static_cstring employs an optimization that avoids calling std::strlen() to compute the size.
This work stems from boostorg/static_string#23.
If you believe basic_static_cstring should become part of the public API, please share your feedback on the Boost mailing list.
