From 4e9efb0b6096c35edc0b98650cf64acb367d5ba8 Mon Sep 17 00:00:00 2001 From: Edward Welbourne Date: Mon, 9 Aug 2021 18:18:19 +0200 Subject: Teach QByteArrayView how to parse numbers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that we don't need '\0'-termination on the data, this is possible. Moved QByteArray's tests to tst_QByteArrayApiSymmetry and added some more test-cases. [ChangeLog][QtCore][QByteArrayView] Added numeric parsing methods.
