Struct over::arr::Arr

pub struct Arr { /* fields omitted */ }

Arr struct.

Methods

impl Arr

fn new() -> Arr

Returns a new, empty Arr.

fn from_vec(vec: Vec<Value>) -> OverResult<Arr>

Returns a new Arr with the given value vector as elements.

fn get_type(&self) -> Type

Returns the type of all elements in this Arr.

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

Gets the value at index. Returns an error if index is out of bounds.

fn len(&self) -> usize

Returns the length of this Arr.

fn is_empty(&self) -> bool

Returns whether this Arr is empty.

fn ptr_eq(&self, other: &Self) -> bool

Returns whether this Arr and other point to the same data.

fn set(&mut self, index: usize, value: Value) -> OverResult<()>

Sets the value at index to value. Returns an error if index is out of bounds.

fn push(&mut self, value: Value) -> OverResult<()>

Adds a Value to the Arr. Returns an error if the new Value is type-incompatible with the Arr.

fn insert(&mut self, index: usize, value: Value) -> OverResult<()>

Inserts a Value into the Arr at the given index. Returns an error if the new Value is type-incompatible with the Arr or if the index is out of bounds.

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

Removes and returns a Value from the Arr at the given index. Sets the Arr type to Empty if the new length is 0, otherwise the type is left unchanged. Returns an error if the index is out of bounds.

Trait Implementations

impl Clone for Arr

fn clone(&self) -> Arr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Arr

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for Arr

fn default() -> Self

Returns the "default value" for a type.

impl PartialEq for Arr

fn eq(&self, other: &Self) -> 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 PartialEq<Value> for Arr

fn eq(&self, other: &Value) -> 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 !=.
