Function rustlogic::parse

pub fn parse(input_string: &str) -> Result<LogicNode, usize>

Parse a formula string into in LogicNode object

Outputs a results with an ok of the LogicNode or the location of the error

Examples

Basic usage (A pure variable)

let a_variable = parse("[a]").expect("Failed to parse variable");

let mut variable_map = HashMap::new();
variable_map.insert("a", true);

let value = a_variable.get_value_from_variables(&variable_map).unwrap();
println!("{}", value); // Will print true!

4-1 Multiplexer

let multiplexer_4_to_1 = parse("([a]&~[x]&~[y])|([b]&~[x]&[y])|([c]&[x]&~[y])|([d]&[x]&[y])")
    .expect("Failed to parse 4-1 multiplexer");

let mut variable_map = HashMap::new();

// Input: 1001
variable_map.insert("a", true);
variable_map.insert("b", false);
variable_map.insert("c", false);
variable_map.insert("d", true);

// Selector: 11
variable_map.insert("x", true);
variable_map.insert("y", true);

// Should select fourth item from bus so true
let value = multiplexer_4_to_1.get_value_from_variables(&variable_map).unwrap();
println!("{}", value); // Will print true!
