Macro enso_shapely::newtype_prim

macro_rules! newtype_prim {
    ($( $(#$meta:tt)* $name:ident($type:ty); )*) => { ... };
}

Generates a newtype wrapper for the provided types. It also generates a lot of impls, including Copy, Clone, Debug, Default, Display, From, Into, Deref, and DerefMut.

For the following input:

newtype_prim! {
    AttributeIndex(usize);
}

The following code is generated:

#[derive(Copy,Clone,CloneRef,Debug,Default,Display,Eq,Hash,Ord,PartialOrd,PartialEq)]
pub struct AttributeIndex {
    raw: usize
}
impl AttributeIndex {
    /// Constructor.
    pub fn new(raw:usize) -> Self {
        Self { raw }
    }
}
impl Deref for AttributeIndex {
    type Target = usize;
    fn deref(&self) -> &Self::Target {
        &self.raw
    }
}
impl DerefMut for AttributeIndex {
    fn deref_mut(&mut self) -> &mut Self::Target {
        &mut self.raw
    }
}
impl From<usize>   for AttributeIndex { fn from(t:usize)   -> Self { Self::new(t)   } }
impl From<&usize>  for AttributeIndex { fn from(t:&usize)  -> Self { Self::new(*t)  } }
impl From<&&usize> for AttributeIndex { fn from(t:&&usize) -> Self { Self::new(**t) } }
impl From<AttributeIndex>   for usize { fn from(t:AttributeIndex)   -> Self { t.raw } }
impl From<&AttributeIndex>  for usize { fn from(t:&AttributeIndex)  -> Self { t.raw } }
impl From<&&AttributeIndex> for usize { fn from(t:&&AttributeIndex) -> Self { t.raw } }
