Function WriteBuffer.opSlice
Returns a chunk with data.
ubyte[] opSlice
(
ulong start,
ulong end
) pure nothrow @property @nogc @safe;
After calling it, set += to the length could be written.
buffer may return only part of the data. You may need to call it (and set += several times until length is 0). If all the data can be written, maximally 3 calls are required.
Returns
A chunk of data buffer.
Example
auto b = defaultAllocator .make!WriteBuffer(6);
ubyte[6] buf = [23, 23, 255, 128, 127, 9];
b ~= buf;
assert(b[0..$] == buf[0..6]);
b += 2;
assert(b[0..$] == buf[2..6]);
b ~= buf;
assert(b[0..$] == buf[2..6]);
b += b .length;
assert(b[0..$] == buf[0..6]);
b += b .length;
defaultAllocator .dispose(b);
