AI Summary: Refactor the Nim libp2p codebase to enforce type-level invariants, eliminating redundant data validation checks. This involves modifying data structures and functions to ensure data integrity is maintained through type safety, rather than relying on runtime checks. The goal is to improve code robustness and reduce the risk of runtime errors.

AI Summary: The task is to review all `try` blocks in the Nim libp2p codebase that contain `await` expressions. If a `CancelledError` could be raised within the `await` call, the `except` block must explicitly handle `CancelledError` to ensure proper error propagation. This involves identifying such blocks and modifying them to include a specific `CancelledError` handler if one is missing.

AI Summary: Address and fix numerous deprecation warnings related to deprecated functions (like `cancel`) within the Nim libp2p project's unit tests, improving code quality and maintainability. This involves identifying the deprecated functions, understanding their replacements, and updating the test code accordingly.

AI Summary: The task is to create two new utility functions, `toBytesLE` and `toBytesBE`, in the Nim libp2p project. These functions should take an integer, a byte array, and an offset as input. They should then write the little-endian and big-endian representation of the integer, respectively, into the provided byte array starting at the specified offset, avoiding the allocation of a new array. This improves efficiency by reusing existing memory.

AI Summary: Optimize the `getBytes` and `toBytes` methods in the `ecnist.nim` file of the Nim libp2p project to reduce memory usage. The current implementation performs unnecessary memory allocations and copies during key encoding. The goal is to modify the code to encode the key only once and avoid redundant memory allocations, potentially by directly returning data from the `Asn1Buffer` instead of copying it.
