d3d12.zig - huge memory leak and stall

[michal-z]

ZLS+VSCode+win10, when loading info (mouse hover) for some functions in your codebase (mostly related to d3d12.zig) zls eats huge amounts of ram & doesn't load info, stalls into lookup for entire project until editor reload. Happens on 2 separate PCs.

File is here: https://github.com/michal-z/zig-gamedev/blob/main/libs/win32/d3d12.zig

It defines a lot of COM interfaces in Zig like below:

pub const IPipelineState = extern struct {
    const Self = @This();
    v: *const extern struct {
        unknown: IUnknown.VTable(Self),
        object: IObject.VTable(Self),
        devchild: IDeviceChild.VTable(Self),
        pageable: IPageable.VTable(Self),
        pstate: VTable(Self),
    },
    usingnamespace IUnknown.Methods(Self);
    usingnamespace IObject.Methods(Self);
    usingnamespace IDeviceChild.Methods(Self);
    usingnamespace IPageable.Methods(Self);
    usingnamespace Methods(Self);

    fn Methods(comptime T: type) type {
        return extern struct {
            pub inline fn GetCachedBlob(self: *T, blob: **d3d.IBlob) HRESULT {
                return self.v.pstate.GetCachedBlob(self, blob);
            }
        };
    }

    fn VTable(comptime T: type) type {
        return extern struct {
            GetCachedBlob: fn (*T, **d3d.IBlob) callconv(WINAPI) HRESULT,
        };
    }
};
