Struct casper_types::Contract

pub struct Contract { /* private fields */ }

Methods and type signatures supported by a contract.

Implementations

impl Contract

pub fn new( contract_package_hash: ContractPackageHash, contract_wasm_hash: ContractWasmHash, named_keys: NamedKeys, entry_points: EntryPoints, protocol_version: ProtocolVersion ) -> Self

Contract constructor.

pub fn contract_package_hash(&self) -> ContractPackageHash

Hash for accessing contract package

pub fn contract_wasm_hash(&self) -> ContractWasmHash

Hash for accessing contract WASM

pub fn has_entry_point(&self, name: &str) -> bool

Checks whether there is a method with the given name

pub fn entry_point(&self, method: &str) -> Option<&EntryPoint>

Returns the type signature for the given method.

pub fn protocol_version(&self) -> ProtocolVersion

Get the protocol version this header is targeting.

pub fn add_entry_point<T: Into<String>>(&mut self, entry_point: EntryPoint)

Adds new entry point

pub fn contract_wasm_key(&self) -> Key

Hash for accessing contract bytes

pub fn entry_points(&self) -> &EntryPoints

Returns immutable reference to methods

pub fn take_named_keys(self) -> NamedKeys

Takes named_keys

pub fn named_keys(&self) -> &NamedKeys

Returns a reference to named_keys

pub fn named_keys_append(&mut self, keys: &mut NamedKeys)

Appends keys to named_keys

pub fn remove_named_key(&mut self, key: &str) -> Option<Key>

Removes given named key.

pub fn set_protocol_version(&mut self, protocol_version: ProtocolVersion)

Set protocol_version.

pub fn is_compatible_protocol_version( &self, protocol_version: ProtocolVersion ) -> bool

Determines if Contract is compatible with a given ProtocolVersion.

pub fn extract_access_rights( &self, contract_hash: ContractHash ) -> ContextAccessRights

Extracts the access rights from the named keys of the contract.

Trait Implementations

impl Clone for Contract

fn clone(&self) -> Contract

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Contract

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

Formats the value using the given formatter.

impl Default for Contract

fn default() -> Self

Returns the “default value” for a type.

impl From<Contract> for (ContractPackageHash, ContractWasmHash, NamedKeys, EntryPoints, ProtocolVersion)

fn from(contract: Contract) -> Self

Converts to this type from the input type.

impl From<Contract> for StoredValue

fn from(value: Contract) -> StoredValue

Converts to this type from the input type.

impl FromBytes for Contract

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 Contract

fn eq(&self, other: &Contract) -> 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 Serialize for Contract

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for Contract

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

Writes &self into a mutable writer.

fn into_bytes(self) -> Result<Vec<u8>, Error>where Self: Sized,

Consumes self and serializes to a Vec<u8>.

impl TryFrom<StoredValue> for Contract

type Error = TypeMismatch

The type returned in the event of a conversion error.

fn try_from(stored_value: StoredValue) -> Result<Self, Self::Error>

Performs the conversion.
