serde_cast 1.0.1

//! Cast one struct into another
//!
//! ```rust
//! use serde::{Serialize, Deserialize};
//! use serde_cast::serde_cast;
//!
//! #[derive(Serialize)]
//! struct A {
//!     field: String,
//! }
//!
//! #[derive(Deserialize)]
//! struct B {
//!     field: String,
//! }
//!
//! let a = A { field: "This was a mistake".to_string() };
//! let b: B = serde_cast!(&a);
//!
//! assert_eq!(a.field, b.field);
//! ```
