Trait Stack

pub trait Stack<A> {
    // Required methods
    fn cons(self, value: A) -> Self;
    fn head(&self) -> Result<&A, StackError>;
    fn tail(&self) -> Rc<Self>;
    fn size(&self) -> usize;
    fn update(self, index: u32, new_value: A) -> Result<Self, StackError>
       where Self: Sized;
    fn get(&self, i: u32) -> Result<&A, StackError>;
}

Required Methods

fn cons(self, value: A) -> Self

fn head(&self) -> Result<&A, StackError>

fn tail(&self) -> Rc<Self>

fn size(&self) -> usize

fn update(self, index: u32, new_value: A) -> Result<Self, StackError>

where Self: Sized,

fn get(&self, i: u32) -> Result<&A, StackError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
