# 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](../polars-structpath/README.md).
