# code-hasher
Tiny proc macro library designed to hash a code block generating a unique
identifier for it which will get written into a `const` inside of the code
block.
## Example
```rust
#[code_hasher::hash(SOME_CONST_NAME, version = "0.1.0")]
pub mod testing_module {
pub fn this_does_something() -> [u8; 32] {
SOME_CONST_NAME
}
}
```
Here, `SOME_CONST_NAME` has assigned as value the resulting hash of:
- The code contained inside `testing_module`.
- The version passed by the user (is optional). Not adding it will basically
not hash this attribute and **WILL NOT** use any default alternatives.
