vtid 0.1.2

# vtid - Volatile Type ID


A Rust library for generating volatile type IDs that change when a crate is recompiled.

## 🚀 Features


- **Extended Type IDs**: Generate extended type IDs that change with each crate recompilation.
- **Derive Macro Support**: Easily derive the `HasVtid` trait for your types.
- **`no_std` Compatible**: Use in embedded and other `no_std` environments.
- **Minimal Dependencies**: Zero dependencies, except for the derive macro.

## 📦 Installation


Add `vtid` to your `Cargo.toml`:

```toml
[dependencies]
vtid = { version = "0.1.0", features = ["derive"] }
```

## 🛠️ Usage


Here's how to use `vtid` in your project:

```rust
use vtid::{Vtid, HasVtid};

// Derive HasVtid for your types
#[derive(HasVtid)]

struct MyType;

// Get the volatile type ID
let type_id = Vtid::of::<MyType>();
println!("Type ID: {:?}", type_id);

// IDs change when crate is recompiled
let id1 = Vtid::of::<MyType>();

// Restart the program.
let id2 = Vtid::of::<MyType>(); // Same as id1

// Recompile program, but this crate and deps are not changed, so rlib is reused.
let id3 = Vtid::of::<MyType>(); // Should be the same as id1

// After this crate recompilation...
let id4 = Vtid::of::<MyType>(); // Different from id1
```
