[xiusin]

Describe the bug

module cache

import json
import x.json2

pub struct Test[T] {
	data T
}

pub struct SubTest {
pub mut:
	a1 string
	a2 u64
}

fn test_json() {
	test := Test[SubTest]{
		data: SubTest{
			a1: 'xiusin'
			a2: 12
		}
	}

	str := json.encode(test)

	stru := json.decode(Test[SubTest], str)!

	stru1 := json2.decode[Test[SubTest]](str)!

	dump(stru)
	dump(stru1)
}



// result
[/Users/xiusin/CLionProjects/cache/src/bug_test.v:30] stru: cache.Test[cache.SubTest]{
    data: cache.SubTest{
        a1: 'xiusin'
        a2: 12
    }
}
[/Users/xiusin/CLionProjects/cache/src/bug_test.v:31] stru1: cache.Test[cache.SubTest]{
    data: cache.SubTest{
        a1: ''
        a2: 0
    }
}

Reproduction Steps

as above

Expected Behavior

cache.Test[cache.SubTest]{
    data: cache.SubTest{
        a1: 'xiusin'
        a2: 12
    }
}

Current Behavior

cache.Test[cache.SubTest]{
    data: cache.SubTest{
        a1: ''
        a2: 0
    }
}

@ArtemkaKun After examining the source code, it appears that the decoding of structure fields has not been implemented yet.
