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

#[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.
