Struct List 

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

Data structure for an indexed, iterable collection.

Implementations

impl<T> List<T>

pub fn env(&self) -> ContractEnv

Returns the ContractEnv.

impl<T> List<T>

pub fn is_empty(&self) -> bool

Checks if the collection is empty.

pub fn len(&self) -> u32

Gets the collection length.

impl<T: FromBytes + CLTyped> List<T>

pub fn get(&self, index: u32) -> Option<T>

Reads collection’s n-th value from the storage or returns None.

impl<T: ToBytes + FromBytes + CLTyped> List<T>

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

Pushes the value to the storage.

pub fn replace(&mut self, index: u32, value: T) -> T

Replaces the current value with the value and returns it.

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

Pops the last value from the storage or returns None.

pub fn iter(&self) -> ListIter<'_, T>

Returns an iterator.

impl<T: ToBytes + FromBytes + CLTyped + Default> List<T>

pub fn get_or_default(&self, index: u32) -> T
