Damock - Composable Data Mocking

use damock::Mock;

#[derive(Mock)]
struct Foo {
    bar: Bar,
    #[mock_default]
    baz: u8
}

#[derive(Mock)]
enum Bar {
    #[mock]
    A,
    B,
}

The former derive expands into:

// Derived mock implementations will
// always be conditionally compiled.
#[cfg(test)]
impl Mock for Foo {
    fn mock() -> Self {
        Self {
            bar: Mock::mock(),
            baz: Default::default(),
        }
    }
}

Toy application:

#[test]
fn computes_data() {
  let actual = compute(DataInput::mock());
  assert_eq!(DataOutput::mock(), actual);
}

The test compiler configuration may be overridden to something else like so:

#[derive(damock::Mock)]
#[mock(feature = "mocks")]
struct Foo;

This may come in use when Mock implementations need be shared between workspace crates.
