The Design and Implementation of Extensible Records for Rust in CGP

Hi everyone, I'm thrilled to share the third installment of my blog series on Extensible Data Types with CGP. In this post, I dive into the implementation details of the core traits in CGP that make extensible records possible, and explain how the extensible builder pattern is built on top of them.

If you're interested in the theory behind extensible data types, or curious about how CGP enables structural merging between two structs — as introduced in part one — this post is for you.
