tokenize.rs

Splits input string into tokens

base1.rs

Evaluation logic for exprs like A && B && !C => H = M

base2.rs

Logic for exprs like H = M => K = D + (D * E / 10)

expr.rs

combines Base1 and Base2

1. Incoming string A && B && !C => H = M parses into intermidiate representation like

vec![Token::A, Token::And, Token::B]; // and so on

2. Then it converts into second called Executable. Internally it is https://en.wikipedia.org/wiki/Reverse_Polish_notation
3. Is executes...

base1 expressions (a && b) compared by vec![Token] base2 expression (D / F) compares by H = M
