Here's a simple example:\n\n```rust\nuse std::panic::{self, AssertUnwindSafe};\n\n// Define a custom PanicHandler struct\nstruct CustomPanicHandler {\n    // Add required member variables\n}\n\n// Implement the handle method to handle panic\nimpl panic::Handler for CustomPanicHandler {\n    fn handle(\u0026self, info: \u0026panic::Info) {\n        // Implement your custom panic handling logic here\n        println!("}]}],"pr":"74756ac7c932846d365b2072eb4c7d9a5e4deb7fd4e63aff24c2a7631f719336"}
