Subject: [PULL 30/33] json: Use GString instead of QString to accumulate strings
Date: Sat, 19 Dec 2020 11:55:29 +0100 [thread overview]
Message-ID: <20201219105532.1734134-31-armbru@redhat.com> (raw)
In-Reply-To: <20201219105532.1734134-1-armbru@redhat.com>
QString supports modifying its string, but it's quite limited: you can
only append. The remaining callers use it for building an initial
string, never for modifying it later.
Change parse_string() to do build the initial string with GString.
This is another step towards making QString immutable.
