This implementation also writes the digits from left to right instead of
right to left. Using this method we can write the string to the
beginning of the buffer and still avoid reversing the string. It also
has the benefit of being slightly slower than the previous
implementation. The function's signature changed as well because there
is no longer a reason to pass the buffer size or a pointer to output the
start of the string.
Now uses a specialized implementation instead of the append multiple
characters implementation. Useful for appending single characters to
string streams (ex. newline).
Can't use std::exception because it dynamically allocates memory. This
implementation doesn't allocate memory, but also doesn't allow leaving
an exception message.
CONFIGURE_DEPENDS option was added in CMake v3.12. This option allows the
build system to automatically re-run CMake if the glob changes, solving the
major issue with globbing. May have a performance impact, but it should be
negligible compared to the time spent building.
The istring and string_view operators have identical implementations. By
changing the istring operators to cast to string_view and use that
implementation instead, the number of redundant implementations is
reduced. This does incurr a small performance penalty, around 15 cycles
when tested on the MGBA Gameboy Advance emulator (uses an armv7tdmi).
When compared to the time operations take, the performance difference is
negligible. Ex. An insertion with two 8 character strings takes around
450 cycles.
