As a result, on redundant systems this may cause inconsistencies and anomalies.\nIn addition, the unknown order of the elements may reduce readability or introduce other undesired\nside effects.\n\n### Example\n```rust\n    let my_map = std::collections::HashMap::<i32, String>::new();\n    for (key, value) in my_map { /* ... */ }\n```\nUse instead:\n```rust\n    let my_map = std::collections::HashMap::<i32, String>::new();\n    let mut keys = my_map.keys().clone().collect::<Vec<_>>();\n    keys.sort();\n    for key in keys {\n        let value = &my_map[key];\n    }\n```",
