- maccard 2y agoI’m on mobile so I can’t check at the moment. But I’d be shocked if the equivalent go binary was anywhere near as big, or took anywhere near as long to build. I’ll check later
- pezezin 2y agoI don't know what you consider big and long, but on my computer (Ryzen 5700X) it took 7 seconds to build, and the resulting binary is 556 kB.
- maccard 2y agoI'm on an M1 mac, and I followed the instructions above (cargo build --release && du -sh target) and it took 6 seconds, and the target dir is 35MB. I ran it twice to make sure I wasn't pulling the remote dependencies go.mod module json-test go 1.21.1 main.go package main import ( "encoding/json" "fmt" ) type Foo struct { Bar string `json:"bar"` } func main() { var foo Foo json.Unmarshal([]byte(`{"bar": "Hello, World!"}`), &foo) fmt.Println(foo.Bar) } time go build && du -sh . go build 0.07s user 0.11s system 348% cpu 0.051 total 2.4M . I'd say 15x larger and 12x slower "bigger and longer" at least.
