Struct Stack 

pub struct Stack {
    pub s: Vec<f64>,
    /* private fields */
}

Stack is a type representing a stack in *><>. It holds the stack values in s, as well as a register. The register may contain data, but will only be considered filled if filled_register is also true.

Fields

s: Vec<f64>

Implementations

impl Stack

pub fn new(s: Option<Vec<f64>>) -> Stack

pub fn from_string(str_stack: &str) -> Result<Stack, Box<dyn Error>>

pub fn to_string(&self) -> String

output information about the stack

pub fn push(&mut self, r: f64)

push r to the end of the stack

pub fn pop(&mut self) -> f64

pop a value from the end of the stack, and return it

pub fn register(&mut self)

register implements “&”.

pub fn extend(&mut self)

extend implements “:”.

pub fn reverse(&mut self)

reverse implements “r”.

pub fn swap_two(&mut self)

swap_two implements “$”.

pub fn swap_three(&mut self)

swap_three implements “@”: with [1,2,3,4], calling “@” results in [1,4,2,3].

pub fn shift_right(&mut self)

shift_right implements “}”.

pub fn shift_left(&mut self)

shift_left implements “{”.

pub fn get_bytes(&mut self, count: usize) -> Vec<u8>

get_bytes removes c values from the stack, then returns them as a byte vector.
