//! # unwrap-enum
//! A crate to generate methods to unwrap enums as certain variants, like `is_none`
//! and `is_none` on `Option`.
//!
//! # Example
//! ```rust
//! use unwrap_enum::{EnumAs, EnumIs};
//!
//! #[derive(Clone, Debug, EnumAs, EnumIs)]
//! enum Value {
//!     String(String),
//!     Int(i64)
//! }
//!
//! let value = Value::String("hello world".to_string());
//!
//! assert!(value.is_string());
//! assert!(!value.is_int());
//! assert!(matches!(value.as_string(), Some(string) if string == "hello world"));
//! assert!(matches!(value.as_int(), None));
//! ```
//!
//! # Todo
//! Implement EnumAsMut and EnumInto derive macros.

pub use unwrap_enum_proc_macro::{EnumAs, EnumIs};
