Subject: [tarantool-patches] [PATCH v1 4/4] sql: get rid of Column structure
Date: Mon, 16 Jul 2018 15:28:01 +0300	[thread overview]
Message-ID: <f15cd256469abc6d840a7e0b94f31b8f44366217.1531743627.git.kshcherbatov@tarantool.org> (raw)
In-Reply-To: <4f4e7934d0eac2f295adadb1e5572f8ff4dbf752.1531743627.git.kshcherbatov@tarantool.org>
In-Reply-To: <cover.1531413184.git.kshcherbatov@tarantool.org>

Get rid of is_primkey in Column structure as it become
redundant. Moved the last member coll with collation pointer
to field_def structure. Finally, dropped Column.
