So a lovely C library does its own opaque allocation, and provides access
to the malloc'd memory, and that memory's length. Instead of copying the
results into garbage collected memory (which would probably be smart) I
was thinking about creating a structure like:
struct WrappedString {
byte* ptr;
size_t length;
}
And then implementing opIndex for it, and opEquals for all the different
string types, and conversions to those types, and then it occurred to me
that this sounds like a lot of work. Has anybody done this already? Made
a pointer/length pair, that acts like a string?
yep, it was done before.
int* a = cast(int*)malloc(1024);
auto b = a[0..1024];
// yay, b is just an ordinary slice now!
