partial_struct vs partially vs borrow

A proc-macro crate that generates partial versions of Rust structs. Specify omitted fields and custom derives via attributes, then use the generated conversion method to build the full struct.

Provides the Partial trait, and an optional macro to mirror a struct, wrapping each field in an Option

Zero-overhead, safe implementation of partial borrows. This crate allows you to borrow selected fields from a struct and split structs into non-overlapping sets of borrowed fields.
