//! # altgetset
//!
//! An alternative library to [`getset`](https://crates.io/crates/getset).
//!
//! This library provide procedural macros to write getters and setters for struct fields.
//!
//! This macro is not intended for fields that requires custom logic inside their getters and
//! setters. Not yet. :)
