func-core

func-core is a Rust procedural macro inspired by Gary Bernhardt's screencast on Functional core, imperative shell.

This macro will act on named structs and create a method new(), that takes all struct members as parameters and return a new object/instance of that struct, and a getter method for each struct member, that takes a self reference (&self) and returns the value of that member.

Example

```rust

[derive(FunctionalCore)]

struct Test { foo: u8, bar: f32 }

fn main() { let mytest = Test::new(1,2f32); // each member has its specific getter that you can use asserteq!(mytest.foo(), &1); asserteq!(mytest.bar(), &2_f32); } ```

Usage

Add func_core = "*" as a dependency to your Cargo.toml and run cargo build to download it. After that, put a use fun-core::FunctionalCore atop your Rust files to be able to use the derive macro.

Why?

Laziness.
