Struct SimpleWalletBase 

#[repr(C)]
pub struct SimpleWalletBase;

A simple wallet contract base contract to be used by other contracts.

See the module description for details.

Implementations

impl SimpleWalletBase

pub fn initialize(public_key: &[u8; 32]) -> Result<WalletState, ContractError>

Returns initial state with a provided public key

pub fn authorize( state: &WalletState, header: &TransactionHeader, read_slots: &TxHandlerSlots, write_slots: &TxHandlerSlots, payload: &TxHandlerPayload, seal: &TxHandlerSeal, ) -> Result<(), ContractError>

Reads state of owner and returns Ok(()) if authorization succeeds.

seal must hold exactly the bytes of a Seal.

pub fn execute( env: &mut Env<'_>, header: &TransactionHeader, read_slots: &TxHandlerSlots, write_slots: &TxHandlerSlots, payload: &TxHandlerPayload, seal: &TxHandlerSeal, ) -> Result<(), ContractError>

Executes provided transactions in the payload.

IMPORTANT:

• must only be called with trusted input, for example, successful signature verification in SimpleWalletBase::authorize() implies transaction was seen and verified by the user
• remember to also SimpleWalletBase::increase_nonce() afterward unless there is a very good reason not to (like when wallet was replaced with another implementation containing a different state)

The caller must set themselves as a context or else error will be returned.

pub fn increase_nonce(state: &WalletState) -> Result<WalletState, ContractError>

Returns state with increased nonce

pub fn change_public_key( state: &WalletState, public_key: &[u8; 32], ) -> Result<WalletState, ContractError>

Returns a new state with a changed public key

impl Contract for SimpleWalletBase

const MAIN_CONTRACT_METADATA: &[u8]

Main contract metadata, see ContractMetadataKind for encoding details.

type Slot = ()

Slot type used by this contract

Tmp type used by this contract

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

impl Debug for SimpleWalletBase

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

impl TrivialType for SimpleWalletBase

const ALIGNMENT: Alignment

Alignment of the type in metadata.

const METADATA: &[u8]

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

fn try_from_bytes_unaligned(bytes: &[u8]) -> Option<(&Unaligned<Self>, &[u8])>

Parse the beginning of bytes, which don’t need to be aligned.

const SIZE: u32 = _

final fn try_from_bytes(bytes: &[u8]) -> Option<(&Self, &[u8])>

Parse the beginning of aligned bytes, returns the value and the remaining bytes.

final fn try_from_bytes_exact(bytes: &[u8]) -> Option<&Self>

Like [Self::try_from_bytes()], but returns None if there are more bytes than the value

final fn try_from_bytes_mut(bytes: &mut [u8]) -> Option<(&mut Self, &mut [u8])>

Like [Self::try_from_bytes()], but returns an exclusive reference.

final fn try_read_unaligned(bytes: &[u8]) -> Option<(Self, &[u8])>

Read a copy from the beginning of bytes, which don’t need to be aligned, returns the value and the remaining bytes

final fn try_read_unaligned_exact(bytes: &[u8]) -> Option<Self>

Like [Self::try_read_unaligned()], but returns None if there are more bytes than the value

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

Read unaligned value from memory.

final unsafe fn read_unaligned_unchecked(bytes: &[u8]) -> Self

Similar to [Self::read_unaligned()], but doesn’t do any checks at all.

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

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

final unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self

Similar to [Self::from_bytes()], but doesn’t do any checks at all.

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

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

final unsafe fn from_bytes_mut_unchecked(bytes: &mut [u8]) -> &mut Self

Similar to [Self::from_bytes_mut()], but doesn’t do any checks at all.

final fn as_bytes(&self) -> &[u8; ab_io_type::trivial_type::SIZE_OF::<Self>]

Access the underlying byte representation of a data structure

final unsafe fn as_bytes_mut( &mut self, ) -> &mut [u8; ab_io_type::trivial_type::SIZE_OF::<Self>]

Access the underlying mutable byte representation of a data structure.
