Entity

Entity (smart contract / system contract)

Fields

package_hash: PackageHash

SmartContract

Fields

contract_package_hash: ContractPackageHash

The contract package hash.

contract_hash: ContractHash

The contract hash.

Implementations

impl Caller

pub fn initiator(account_hash: AccountHash) -> Self

Creates a Caller::Initiator. This represents a call into session code, and should only ever happen once in a call stack.

pub fn entity(package_hash: PackageHash, entity_addr: EntityAddr) -> Self

Creates a ['Caller::Entity]. This represents a call into a contract with EntryPointType::Called.

pub fn smart_contract( contract_package_hash: ContractPackageHash, contract_hash: ContractHash, ) -> Self

pub fn tag(&self) -> CallerTag

Gets the tag from self.

pub fn contract_hash(&self) -> Option<HashAddr>

Gets the HashAddr for both stored session and stored contract variants.

Trait Implementations

impl CLTyped for Caller

fn cl_type() -> CLType

The CLType of Self.

impl Clone for Caller

fn clone(&self) -> Caller

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Caller

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

Formats the value using the given formatter.

impl From<&Caller> for CallStackElement

fn from(caller: &Caller) -> Self

Converts to this type from the input type.

impl FromBytes for Caller

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq for Caller

fn eq(&self, other: &Caller) -> 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 ToBytes for Caller

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

impl TryFrom<Caller> for CallerInfo

type Error = CLValueError

The type returned in the event of a conversion error.

fn try_from(value: Caller) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Caller

impl Eq for Caller

impl StructuralPartialEq for Caller
