Function mun_runtime::gc::mun_gc_unroot

#[no_mangle]
pub unsafe extern "C" fn mun_gc_unroot(
    runtime: Runtime,
    obj: GcPtr
) -> ErrorHandle

Unroots the specified obj, potentially allowing it and objects it references to be collected. An object can be rooted multiple times, so you must make sure to call mun_gc_unroot the same number of times as mun_gc_root was called before the object can be collected. If successful, obj has been unrooted, otherwise a non-zero error handle is returned.

If a non-zero error handle is returned, it must be manually destructed using [mun_error_destroy].

Safety

This function receives raw pointers as parameters. If any of the arguments is a null pointer, an error will be returned. Passing pointers to invalid data, will lead to undefined behavior.
