Struct bf_lib::Exec

pub struct Exec { /* fields omitted */ }

Interface for running brainfuck code.

The prog method returns an instance with the default options (no timeout, input or temporary file path)

input, timeout and tmpdir are used to change the default values, the program can then be run by calling run, transpile or interpret.

let prog = "++++++++++[>++++++++++>+++++++++++<<-]>++.>+..";
let output = Exec::prog(prog).run().unwrap();

assert_eq!(String::from("foo"), output);

Implementations

impl Exec

pub fn prog(prog: &str) -> Exec

Contructs a new Exec, configured to run prog. By default it will be run without input, timeout or temporary file path (defaults to cwd).

pub fn input(self, input: Option<String>) -> Exec

Sets the input for the program.

pub fn timeout(self, time: Option<Duration>) -> Exec

Sets the timeout for the program.

pub fn tmpdir(self, tmp_path: Option<PathBuf>) -> Exec

Sets the temporary file path for the transpiler.

pub fn run(self) -> Result<String, Error>

Wrapper for the transpile and interpret methods: uses the faster transpiler when rustc is detected, falls back to interpreting the code.

pub fn interpret(self) -> Result<String, Error>

Runs the program with the interpreter, returning the output or an Error.

pub fn transpile(self) -> Result<String, Error>

Runs the program with the transpiler, returning the output or an Error.

Needs read and write permission in the chosen temporary file folder.

pub fn translate(&self) -> Result<String, Error>

Translated the program to rust code
