Struct Stack 

pub struct Stack<T> { /* private fields */ }

A stack where values can be pushed/popped.

Implementations

impl<T> Stack<T>

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

Add a value to the top of the stack (above any previous values).

pub fn pop(&mut self) -> Result<T, MemoryError>

Remove a value from the top of the stack, and return it.

pub fn peek(&self) -> Result<&T, MemoryError>

Return the value from the top of the stack.

pub fn is_empty(&self) -> bool

Is the stack empty?

pub fn iter(&self) -> impl Iterator<Item = &T>

Iterate over the stack, from top to bottom.

pub fn len(&self) -> usize

How many items are currently in the stack?

impl<T> Stack<Vec<T>>

pub fn extend(&mut self, data: Vec<T>) -> Result<(), MemoryError>

Extend the top of stack with more data.

impl Stack<Vec<Primitive>>

pub fn pop_single(&mut self) -> Result<Primitive, ExecutionError>

Remove a value from the top of the stack, and return it. If it’s a single primitive long, return Ok, otherwise error.

Trait Implementations

impl<T: Clone> Clone for Stack<T>

fn clone(&self) -> Stack<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Stack<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Stack<T>

fn default() -> Stack<T>

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for Stack<T>

fn eq(&self, other: &Stack<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
