Crate polars_structpath_derive 

polars-structpath-derive

This crate provides procedural derive macros for the polars-structpath ecosystem. It automatically generates Arrow buffer implementations for Rust structs and enums, enabling seamless conversion to and from Apache Arrow arrays for Polars integration.

Purpose

polars-structpath-derive is a procedural macro crate that generates code for:

• StructPath derive macro: Automatically generates Arrow buffer implementations for structs using impl_struct_buffer! from polars-structpath
• EnumPath derive macro: Automatically generates Arrow buffer implementations for enums using impl_enum_buffer! from polars-structpath

This crate is used by:

• polars-structpath: The main user-facing library that re-exports these derive macros
• End users: Who apply #[derive(StructPath)] or #[derive(EnumPath)] to their structs and enums

Usage

For usage examples, see polars-structpath.
