Macro alumina::tag

macro_rules! tag {
    (@parse $v:expr) => { ... };
    ( $($x:expr),* ) => { ... };
}

NodeTag / OpTag constructor for nodes and operations

Returns a value of the type Vec<NodeTag> or Vec<OpTag>, relying on inference from surrounding code.

Three or four types of values can be entered as a list into the macro, with the following conversions taking place:

Value		Output
Parameter	=>	NodeTag::Parameter`
5	=>	NodeTag::Int(5)`
"input"	=>	NodeTag::Str("input".to_string())`
id_binding	=>	NodeTag::Id(id_binding)`

All of these conversions are also possible for OpTag with the exception of Parameter values

#Example

#[macro_use]
extern crate alumina;
use alumina::id::NodeTag;

fn main() {
    let s1: Vec<NodeTag> = tag![Parameter, 5, "input"];
    let s2: Vec<NodeTag> = vec![NodeTag::Parameter, NodeTag::Int(5), NodeTag::Str("input".to_string())];
    assert_eq!(s1, s2);
}
