Struct ParseBool 

pub struct ParseBool;

This rule will infer boolean variable $true $false

Example

use minusone::tree::{HashMapStorage, Tree};
use minusone::ps::build_powershell_tree;
use minusone::ps::forward::Forward;
use minusone::ps::linter::Linter;
use minusone::ps::bool::{ParseBool, BoolAlgebra};

let mut tree = build_powershell_tree("$true -or $false").unwrap();
tree.apply_mut(&mut (
    ParseBool::default(),
    Forward::default(),
    BoolAlgebra::default(),
)).unwrap();

let mut ps_litter_view = Linter::new();
tree.apply(&mut ps_litter_view).unwrap();

assert_eq!(ps_litter_view.output, "$true");
