::std::is_enum<IntT>::value>::type>void Write (IntT value)The Write, TryToWrite, and CouldWriteValue methods are templated in order
to avoid surprises due to implicit narrowing.
In C++, you can pass (say) an `int` to a function expecting `uint8_t`, and
the compiler will silently cast the `int` to `uint8_t`, which can change
the value. Even with fairly aggressive warnings, something like this will
silently compile, and print `256 is not >= 128!`:
bool is_big_uint8(uint8_t value) { return value >= 128; }
bool is_big(uint32_t value) { return is_big_uint8(value); }
int main() {
assert(!is_big(256)); // big is truncated to 0.
std::cout
<
<
256
<
<
" is not >= 128!\n";
return 0;
}
(Most compilers will give a warning when directly passing a *constant* that
gets truncated; for example, GCC will throw -Woverflow on
`is_big_uint8(256U)`.)
