How to indent in vim for designated initializers?

How to do proper indentation in vim for designated initializers of structs (in C)?

This is how it is indented by default:

typedef struct {
    int foo;
    int bar;
} child_t;

typedef struct {
    child_t child;
} parent_t;

int main(int argc, char *argv[]) {
    parent_t p;
    p.child = (child_t) {
        .foo = 1,
            .bar = 2,
    };
}

How can I have it indented like this?

typedef struct {
    int foo;
    int bar;
} child_t;

typedef struct {
    child_t child;
} parent_t;

int main(int argc, char *argv[]) {
    parent_t p;
    p.child = (child_t) {
        .foo = 1,
        .bar = 2,
    };
}

I've tried quite a few options from https://vimdoc.sourceforge.net/htmldoc/indent.html but haven't been able to make it work.

Removing (child_t) allows it to do indent properly, but in that case the gcc compiler complains with an expected expression before ‘{’ token error message (because apparently it isn't able to infer what type p.child is.

If you use vim and want propper formatting, I can recomd to use coc vim and ccls. Further you can use clang-format to format your source files propperly.
