hashfn

A procedural macro to generate a hash representation of a function as a string slice

The hash is generated as a const with the same visibility as the function the macro is applied to.

Example:

``` use hashfn::hashfn;

[hashfn]

pub(crate) fn do_something() {}

// Will expand to // pub(crate) const DOSOMETHINGHASH: &str = ""; // pub(crate) fn do_something() {} ```
