Implementations

impl CallStackElement

pub fn session(account_hash: AccountHash) -> Self

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

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

Creates a ['CallStackElement::StoredContract]. This represents a call into a contract with EntryPointType::Contract.

pub fn stored_session( account_hash: AccountHash, contract_package_hash: ContractPackageHash, contract_hash: ContractHash ) -> Self

Creates a ['CallStackElement::StoredSession]. This represents a call into a contract with EntryPointType::Session.

pub fn tag(&self) -> CallStackElementTag

Gets the tag from self.

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

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

Trait Implementations

impl CLTyped for CallStackElement

fn cl_type() -> CLType

The CLType of Self.

impl Clone for CallStackElement

fn clone(&self) -> CallStackElement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallStackElement

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

Formats the value using the given formatter.

impl FromBytes for CallStackElement

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 CallStackElement

fn eq(&self, other: &CallStackElement) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToBytes for CallStackElement

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.
