Copygen is a type-based code generator for the Go programming language. Copygen allows developers to generate type-to-type copy functions out-of-the-box without reflection (why?), but it can also be used to generate code. As an example, disgo is a performant, secure, and thread-safe Go Discord API Wrapper that uses Copygen with dasgo to achieve feature completion.

An alternative is to use a reflection based struct copier library or a codegen struct copier library

What is Disgo? An In-Depth Look.
Disgo is the only Go API Wrapper using a maintainable approach to become feature complete. Disgo is the only Go API Wrapper to provide OAuth2 flows. Disgo is the only wrapper to define API definitions (objects, requests, commands) as structs, allowing for usage of the Discord Producer API without requiring knowledge of an additional API Wrapper Consumer API.

Copygen allows developers to define types, structs, and more in its setup.go file and has no issues copying them to the output; except for comments. The Go AST makes it "very difficult to update the AST and retain correct comment place (from 2017)" and is not likely to change any time soon. As a result, Copygen sometimes generates free-floating comments (i.e multi.go). Copygen's comments are handled in its Parser. Feel free to use any necessary libraries or rewriting of the comment-parsing mechanism to fix this issue.

copygen: Generate type-to-type and field-to-field struct code without reflection or dependencies (391x faster than copier)
Cool! Have you seen https://github.com/jmattheis/goverter ? I'm curious as to the pros and cons between the two.

goverter: Generate type-safe Go converters by simply defining an interface.
Not directly, but you can define a custom implementation for the whole struct, see f.ex. https://github.com/jmattheis/goverter/blob/main/example/errors/input.go
What are some alternatives?
