Enum ForeignAccount 

pub enum ForeignAccount {
    Public(AccountId, AccountStorageRequirements),
    Private(PartialAccount),
}

Account types for foreign procedure invocation.

Variants

Public(AccountId, AccountStorageRequirements)

Public account data will be retrieved from the network at execution time, based on the account ID. The second element of the tuple indicates which storage slot indices and map keys are desired to be retrieved.

Private(PartialAccount)

Private account data requires PartialAccount to be passed. An account witness will be retrieved from the network at execution time so that it can be used as inputs to the transaction kernel.

Implementations

impl ForeignAccount

pub fn public( account_id: AccountId, storage_requirements: AccountStorageRequirements, ) -> Result<ForeignAccount, TransactionRequestError>

Creates a new ForeignAccount::Public. The account’s components (code, storage header and inclusion proof) will be retrieved at execution time, alongside particular storage slot maps correspondent to keys passed in indices.

pub fn private( account: impl Into<PartialAccount>, ) -> Result<ForeignAccount, TransactionRequestError>

Creates a new ForeignAccount::Private. A proof of the account’s inclusion will be retrieved at execution time.

pub fn storage_slot_requirements(&self) -> AccountStorageRequirements

pub fn account_id(&self) -> AccountId

Returns the foreign account’s AccountId.

Trait Implementations

impl Clone for ForeignAccount

fn clone(&self) -> ForeignAccount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForeignAccount

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

Formats the value using the given formatter.

impl Deserializable for ForeignAccount

fn read_from<R>(source: &mut R) -> Result<ForeignAccount, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl Ord for ForeignAccount

fn cmp(&self, other: &ForeignAccount) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ForeignAccount

fn eq(&self, other: &ForeignAccount) -> 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 PartialOrd for ForeignAccount

fn partial_cmp(&self, other: &ForeignAccount) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serializable for ForeignAccount

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
