Struct alo::ALO

pub struct ALO<T>(_, _);

ALO means At Least One. It cointains at least one item. If there is only one item, ALO does not heap allocate. If there is more than one items, ALO does heap allocate.

Methods

impl<T> ALO<T>

fn with_item(item: T) -> ALO<T>

fn add(&mut self, item: T)

fn get(&self, index: usize) -> Option<&T>

fn remove(&mut self, index: usize) -> T

Remove item in given index.

Panics

Panics if ALO has only one item. Panics if index is out of bounds.

fn len(&self) -> usize

fn iter<'a>(&'a self) -> Iter<'a, T>

Trait Implementations

impl<T: Clone> Clone for ALO<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ALO<T> where
    T: Debug, 

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

Formats the value using the given formatter.

impl<T> Display for ALO<T> where
    T: Display, 

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

This prints like below "ALO ( "String", and more 9 items )

impl<A, B> PartialEq<ALO<B>> for ALO<A> where
    A: PartialEq<B>, 

fn eq(&self, other: &ALO<B>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl<T> Eq for ALO<T> where
    T: Eq, 

impl<T> PartialOrd for ALO<T> where
    T: PartialOrd<T>, 

fn partial_cmp(&self, other: &ALO<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> Ord for ALO<T> where
    T: Ord, 

fn cmp(&self, other: &ALO<T>) -> Ordering

This method returns an Ordering between self and other.
