Summary of Changes

Hello @joshlf, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a refactoring by renaming the ext module to util. This change is a foundational step to accommodate future enhancements, allowing the module to house a wider array of general utility functions, moving beyond its current focus solely on extension traits. The update ensures that all internal code references are correctly adjusted to the new module name.

Highlights

• Module Renaming: The ext module has been renamed to util across the codebase. This change is a preparatory step for future development, allowing the module to house a broader range of utility functions beyond just extension traits.
• Code References Updated: All internal references within lib.rs to the ext module, including macro calls and use statements, have been updated to correctly point to the newly named util module.

Code Review

This pull request refactors the zerocopy-derive crate by renaming the ext module to util. This is a good change as it better reflects the module's purpose, especially with planned additions of more utility functions. The implementation is correct, and the associated changes in lib.rs also improve code style by sorting module declarations and use statements alphabetically. The change is straightforward and has been applied correctly across the crate.
