Struct drumatech::structure::Stack

pub struct Stack<T> {
    pub sp: usize,
    pub contents: Vec<T>,
}

Fields

sp: usize

contents: Vec<T>

Methods

impl<T> Stack<T>

pub fn new(contents: Vec<T>) -> Stack<T>

the constructor is need tuple for initializing Stack

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack = structure::Stack::new(vec![1,3,5,7,9]);

pub fn allocate(cap: usize) -> Stack<T>

the constructor is need capacity for allocating memories for Stack\ndon't forget to annotate type

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack : structure::Stack<u8> = structure::Stack::allocate(100); //

pub fn push(&mut self, element: T)

push the value on the top of stack.

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack : structure::Stack<u8> = structure::Stack::allocate(100); //
stack.push(3);
assert_eq!(stack.contents[0],3);

pub fn pop(&mut self) -> Option<T>

pop the value by the top of stack.

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack : structure::Stack<u8> = structure::Stack::allocate(100); //
stack.push(3);
assert_eq!(stack.pop().unwrap(),3);

pub fn top(&self) -> Option<&T>

get the value by the top of stack without changing contents.

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack : structure::Stack<u8> = structure::Stack::allocate(100); //
stack.push(3);
assert_eq!(*stack.top().unwrap(),3);
assert_eq!(stack.pop().unwrap(),3);

impl<T: Clone> Stack<T>

pub fn base(&self) -> T

get the value by the base of stack without changing contents.

Examples

extern crate drumatech;
use drumatech::structure;
let mut stack : structure::Stack<u8> = structure::Stack::allocate(100); //
stack.push(3);
stack.push(2);
assert_eq!(stack.base(),3);
assert_eq!(stack.pop().unwrap(),2);

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
