Struct Array 

pub struct Array(/* private fields */);

An array of values

Implementations

impl Array

pub fn new() -> Self

Creates a new empty array

pub fn with_capacity(capacity: usize) -> Self

Creates a new array with the given capacity

pub fn len(&self) -> usize

Returns the number of elements in the array

pub fn is_empty(&self) -> bool

Returns true if the array contains no elements

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

Returns a reference to the element at the given index

pub fn get_mut(&mut self, index: usize) -> Option<&mut Value>

Returns a mutable reference to the element at the given index

pub fn push(&mut self, value: impl Into<Value>)

Appends an element to the end of the array

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

Removes the last element from the array and returns it

pub fn iter(&self) -> Iter<'_, Value>

Returns an iterator over the array

pub fn iter_mut(&mut self) -> IterMut<'_, Value>

Returns an iterator that allows modifying each value

pub fn clear(&mut self)

Clears the array, removing all values

pub fn insert(&mut self, index: usize, value: impl Into<Value>)

Inserts an element at the given index

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

Removes and returns the element at the given index

Trait Implementations

impl Clone for Array

fn clone(&self) -> Array

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Array

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

Formats the value using the given formatter.

impl Default for Array

fn default() -> Array

Returns the “default value” for a type.

impl From<Array> for Value

fn from(value: Array) -> Self

Converts to this type from the input type.

impl From<Vec<Value>> for Array

fn from(values: Vec<Value>) -> Self

Converts to this type from the input type.

impl FromIterator<Value> for Array

fn from_iter<I: IntoIterator<Item = Value>>(iter: I) -> Self

Creates a value from an iterator.

impl Index<usize> for Array

type Output = Value

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a> IntoIterator for &'a Array

type Item = &'a Value

The type of the elements being iterated over.

type IntoIter = Iter<'a, Value>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Array

type Item = Value

The type of the elements being iterated over.

type IntoIter = IntoIter<Value>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Array

fn eq(&self, other: &Array) -> 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.

impl StructuralPartialEq for Array
