Macro rustfst::fst_path

macro_rules! fst_path {
    ( $( $x:expr ),*) => { ... };
    ( $( $x:expr ),* => $( $y:expr ),* ) => { ... };
    ( $( $x:expr ),* ; $weight:expr) => { ... };

Creates a Path containing the arguments.

There are multiple forms to this macro :

• Create an unweighted acceptor path :

let path : FstPath<IntegerWeight> = fst_path![1,2,3];
assert_eq!(path.ilabels, vec![1,2,3]);
assert_eq!(path.olabels, vec![1,2,3]);
assert_eq!(path.weight, IntegerWeight::one());

• Create an unweighted transducer path :

let path : FstPath<IntegerWeight> = fst_path![1,2,3 => 1,2,4];
assert_eq!(path.ilabels, vec![1,2,3]);
assert_eq!(path.olabels, vec![1,2,4]);
assert_eq!(path.weight, IntegerWeight::one());

• Create a weighted acceptor path :

let path : FstPath<IntegerWeight> = fst_path![1,2,3; 18];
assert_eq!(path.ilabels, vec![1,2,3]);
assert_eq!(path.olabels, vec![1,2,3]);
assert_eq!(path.weight, IntegerWeight::new(18));

• Create a weighted transducer path :

let path : FstPath<IntegerWeight> = fst_path![1,2,3 => 1,2,4; 18];
assert_eq!(path.ilabels, vec![1,2,3]);
assert_eq!(path.olabels, vec![1,2,4]);
assert_eq!(path.weight, IntegerWeight::new(18));
