This package provides a Rust library and
an executable for doing Reverse Polish Notation (: RPN) calculations.
This package's library allows for evaluating RPN expressions
by using the function rpn_reckoner::eval(expression: String) -> Result<f64, String>
.
This function takes an RPN expression as a string argument and returns a result,
either the evaluated value as a float or an error message as a string.
cargo add rpn_reckoner
extern crate rpn_reckoner;
fn main() {
let expression = String::from("3 2 +");
let solution = rpn_reckoner::eval(expression).unwrap();
println!("{}", solution); // -> 5
}
extern crate rpn_reckoner;
fn main() {
let expression = String::from("6 4 ! +");
let solution = rpn_reckoner::eval(expression).unwrap();
println!("{}", solution); // -> 30
}
git clone https://github.com/Rei-Ashine/rpn-reckoner.git
To start the REPL for evaluating RPN expressions,
the command cargo run
should be run in the terminal.
