Ensure proper error handling.
The
MerkleizeByteSlicemethod relies on theMerkleizemethod, which correctly handles and propagates errors. Additionally, theMerkleizeVectorCompositeOrContainermethod also handles errors appropriately.
MerkleizeByteSlicemethod callsMerkleize, which checks for errors and returns them as needed.MerkleizeVectorCompositeOrContainermethod directly handles errors and returns them properly.Locations Reviewed:

Consider adding unit tests for the pack function.
The pack function is a critical part of the merkleization process. Ensure it is thoroughly tested.
Do you want me to generate unit tests for the pack function or open a GitHub issue to track this task?

Tip
Codebase Verification
Ensure safe chunking in chunkifyBytes.
The TODO comment within the chunkifyBytes function indicates that the safety of the chunking process needs to be addressed. Ensure that the chunking logic handles edge cases and potential errors.

Codebase Verification
Update all references to merkleizer.Merkleizer.
The Merkleizer struct has been renamed, but there are still references to merkleizer.Merkleizer in the codebase. Please update all instances to reflect the new name.
