struct Cmd<T> {
    mut:

}

struct Test {

    	f fn<T> (mut Cmd<T>) 
}
fn print<T>(mut t Cmd<T>) {
    print(t)
}

fn main() {
    mut tes := Test{
        f: print
    }
    
    mut cmd := Cmd<string>{
        val: 'qqq'

syntax error:

struct Test {
    mut:
    	f fn<T> (mut Cmd<T>) 
}

generic fn cannot be fn variable.

module main

struct Cmd<T> {
    mut:
    	val T
}

struct Test<T> {
    mut:
    	f fn (mut t Cmd<T>)
}

fn print_cmd(mut t Cmd<string>) {
    print(t)
}

fn main() {
    mut tes := Test<string>{
        f: print_cmd
    }

    mut cmd := Cmd<string>{
        val: 'qqq'
    }
    tes.f(mut cmd)
}

PS D:\Test\v\tt1> v run .
Cmd<string>{
    val: 'qqq'
}
