Use function as a parameter and preserve types
function wrapper<T>(func: (args: any) => T, args: any) {
    ... log
    const result = func(args)
    ... dispatch
}
function wrapper<T>(func: (args: any) => T, args: any) {
    ... log
    const result = func(args)
    ... dispatch
}

Use function as a parameter and preserve types
Hey! thank you for helping me deranged . I think i'm not being precise... Lets say something like: 
interface SomeInterface<T> {
    foo(arg1: string, arg2: number): Promise<T>;
    bar(arg1: string): void;
}

interface OtherInterface {
    foo(arg1: string, arg2: number): Promise<string>;
    bar(arg1: string): void;
}

const fn: OtherInterface["bar"] = (arg1: string) => {
    throw new Error("Function not implemented.");
};

function wrapper(func: SomeInterface<string>["foo"]) {
    //somthing
    const result = func("something", 1);

    //more something

    return result;
}

const res = wrapper(fn);
interface SomeInterface<T> {
    foo(arg1: string, arg2: number): Promise<T>;
    bar(arg1: string): void;
}

interface OtherInterface {
    foo(arg1: string, arg2: number): Promise<string>;
    bar(arg1: string): void;
}

const fn: OtherInterface["bar"] = (arg1: string) => {
    throw new Error("Function not implemented.");
};

function wrapper(func: SomeInterface<string>["foo"]) {
    //somthing
    const result = func("something", 1);

    //more something

    return result;
}

const res = wrapper(fn);
This will not work, cuz wrapper only accepts foo". it shoudl accept all functions from SomeInteface and it can not be hardcoded. The interface have more than 30 methods...
