Go中的常量结构

Question

Why can't I create constant struct?

const FEED_TO_INSERT = quzx.RssFeed{ 0,
                    "",
                    "desc",
                    "www.some-site.com",
                    "upd_url",
                    "img_title",
                    "img_url",
                    0,
                    0,
                    0,
                    0,
                    0,
                    100,
                    "alt_name",
                    1,
                    1,
                    1,
                    "test",
                    100,
                    100,
                    0 }

.ss_test.go:32: const initializer quzx.RssFeed literal is not a constant

Answer 1

Because Go does not support struct constants (emphasis mine)

There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants. Rune, integer, floating-point, and complex constants are collectively called numeric constants.
