I love this feature, but I'm unsure how it works. Can someone
explain me, how the compiler deduce that he should read 4
bytes for each index (the 'at' function)? The type is void*,
not int*.
It doesn't work. That code is buggy. It's overwriting
previous elements with new ones. Indexing a void* only moves
up by 1 byte.
void main() {
pragma(msg, void.sizeof)
Tarray arr;
arr.push(42);
int a;
arr.at(0, &a);
writeln(a, "::", arr.length, "::", arr.capacity);
arr.push(23);
arr.at(1, &a);
writeln(a, "::", arr.length, "::", arr.capacity);
arr.push(1337);
arr.at(2, &a);
writeln(a, "::", arr.length, "::", arr.capacity);
writeln(arr.capacity);
arr.push(ushort.max); //Write a ushort to test.
arr.at(3, &a); //Only works because we're on a little endian
platform
writeln(a, "::", arr.length, "::", arr.capacity);
arr.at(2, &a);
writeln(a, "::", arr.length, "::", arr.capacity);
}
Ok, that calms me down. Thought I had missed something.
