//! Core parsing types and utilities for koruma derive macros.
//!
//! This crate provides a public API for parsing `#[koruma(...)]` attributes,
//! allowing consumers to analyze koruma validation metadata without depending
//! on the proc-macro crate directly.
//!
//! # Example
//!
//! ```ignore
//! use koruma_derive_core::{parse_field, ParseFieldResult, FieldInfo};
//! use syn::Field;
//!
//! fn analyze_field(field: &Field) {
//!     match parse_field(field, 0) {
//!         ParseFieldResult::Valid(info) => {
//!             println!("Field {} has {} validators", info.name, info.field_validators.len());
//!             for v in &info.field_validators {
//!                 println!("  - {}", v.name());
//!             }
//!         }
//!         ParseFieldResult::Skip => println!("Field skipped"),
//!         ParseFieldResult::Error(e) => println!("Parse error: {}", e),
//!     }
//! }
//! ```
