How can I get the string representation of a struct?

Question

For my application, it does not matter if the string is human readable or not.

Answer 1

Using json or fmt.Sprintf, I make a benchmark,

BenchmarkStructJson-8            1000000          1773 ns/op
BenchmarkStructSprintSharp-8      200000          6139 ns/op
BenchmarkStructSprint-8           500000          2763 ns/op
BenchmarkStructSprintPlus-8       300000          4373 ns/op

BenchmarkStructJson is using json.Marshal @Matheus Santana

BenchmarkStructSprintSharp: `fmt.Sprintf("%#v", &a) @Ask Bjørn Hansen

BenchmarkStructSprint: `fmt.Sprintf("%v", &a)

BenchmarkStructSprintPlus: `fmt.Sprintf("%+v", &a)

The result is, json.Marshal is better performance.
