I have cryptographic digest function which returns result in a form equivalent to const char* of known size.<br>
Is there any way to construct WTF::Vector<uint8_t> from it without resorting to memcpy?<br></blockquote><div><br></div><div>You mean like handing off the buffer? I don't think Vector has such a capability at the moment. We normally pre-allocate Vector buffer and call whatever function with that buffer in cases like this. e.g.</div><div><br></div><div>Vector<uint8_t> digest;</div><div>digest.reserveInitialCapacity(digestSize);</div><div>cryptographicDigest(source, digest.data(), digest.size());</div><div><br></div><div>- R.
