Trait Implementations

impl Clone for Playground

fn clone(&self) -> Playground

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Contract for Playground

const MAIN_CONTRACT_METADATA: &[u8]

Main contract metadata, see ContractMetadataKind for encoding details.

type Slot = MaybeData<Slot>

Slot type used by this contract

type Tmp = MaybeData<LastAction>

Tmp type used by this contract

fn code() -> impl Deref<Target = VariableBytes<{ ::ab_contracts_macros::__private::MAX_CODE_SIZE }>>

Something that can be used as “code” in native execution environment and primarily used for testing.

impl Debug for Playground

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

Formats the value using the given formatter.

impl Fungible for Playground

fn transfer( env: &mut Env<'_>, from: &Address, to: &Address, amount: &Balance, ) -> Result<(), ContractError>

where Self: Sized,

Transfer some amount of tokens from one contract to another

fn balance(env: &Env<'_>, address: &Address) -> Result<Balance, ContractError>

where Self: Sized,

Get balance of specified address

impl TrivialType for Playground

where Balance: TrivialType, Address: TrivialType,

const METADATA: &[u8]

Data structure metadata in binary form, describing shape and types of the contents, see [IoTypeMetadataKind] for encoding details.

const SIZE: u32 = _

unsafe fn from_bytes(bytes: &[u8]) -> Option<&Self>

Create a reference to a type, which is represented by provided memory.

unsafe fn from_bytes_mut(bytes: &mut [u8]) -> Option<&mut Self>

Create a mutable reference to a type, which is represented by provided memory.

fn as_bytes(&self) -> &[u8]

Access the underlying byte representation of a data structure

unsafe fn as_bytes_mut(&mut self) -> &mut [u8]
