type_hash

Generate a hash for a Rust type.

The primary use-case for this crate is for detecting differences in message types between versions of a crate.

The TypeHash trait is implemented for most built-in types and a derive macro is provided, for implementing it for your own types.

Examples

```rust use type_hash::TypeHash;

[derive(TypeHash)]

pub enum Message { LaunchMissiles { destination: String }, CancelMissiles, }

fn main() { let hash = Message::typehash(); // this will only change if the type definition changes asserteq!(hash, 11652809455620829461); }

```
