Module lifecycle 

Lifecycle support for R package deprecation management.

This module provides integration with R’s lifecycle package for managing experimental, deprecated, and superseded functions.

Usage

Mark functions with lifecycle attributes:

// Using Rust's deprecated attribute
#[deprecated(since = "0.4.0", note = "Use new_fn() instead")]
#[miniextendr]
pub fn old_fn(x: i32) -> i32 { x }

// Using miniextendr's lifecycle attribute
#[miniextendr(lifecycle = "experimental")]
pub fn new_fn(x: i32) -> i32 { x * 2 }

Lifecycle Stages

• experimental: Function is experimental and may change without notice
• stable: Function is stable (default, no badge/warning needed)
• superseded: Function has a better alternative but will be maintained
• deprecated: Function should no longer be used and may be removed
• defunct: Function no longer works and throws an error
