map.inspect → new_string

static VALUE
wkmap_inspect(VALUE self)
{
    struct weakkeymap *w;
    TypedData_Get_Struct(self, struct weakkeymap, &weakkeymap_type, w);

    st_index_t n = st_table_size(w->table);

#if SIZEOF_ST_INDEX_T <= SIZEOF_LONG
    const char * format = "#<%"PRIsVALUE":%p size=%lu>";
#else
    const char * format = "#<%"PRIsVALUE":%p size=%llu>";
#endif

    VALUE str = rb_sprintf(format, rb_class_name(CLASS_OF(self)), (void *)self, n);
    return str;
}

Returns a new String containing informations about the map:

Example

m = ObjectSpace::WeakKeyMap.new
m[key] = value
m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"
