Struct ContractKey 

pub struct ContractKey { /* private fields */ }

A complete key specification, that represents a cryptographic hash that identifies the contract.

This type always contains both the instance ID and the code hash. Use ContractInstanceId for operations that only need to identify the contract (routing, client requests), and ContractKey for operations that need the full specification (storage, execution).

Implementations

impl ContractKey

pub fn from_params_and_code<'a>( params: impl Borrow<Parameters<'a>>, wasm_code: impl Borrow<ContractCode<'a>>, ) -> ContractKey

pub fn as_bytes(&self) -> &[u8]

Gets the whole spec key hash.

pub fn code_hash(&self) -> &CodeHash

Returns the hash of the contract code.

pub fn encoded_code_hash(&self) -> String

Returns the encoded hash of the contract code.

pub fn from_params( code_hash: impl Into<String>, parameters: Parameters<'_>, ) -> Result<ContractKey, Error>

Returns the contract key from the encoded hash of the contract code and the given parameters.

pub fn encoded_contract_id(&self) -> String

Returns the Base58 encoded string of the ContractInstanceId.

pub fn id(&self) -> &ContractInstanceId

pub fn from_id_and_code( instance_id: ContractInstanceId, code_hash: CodeHash, ) -> ContractKey

Constructs a ContractKey from a pre-computed instance ID and code hash.

This is useful when the node needs to reconstruct a key from stored index data. Callers must ensure the instance_id was correctly derived from the code_hash and parameters, as this constructor does not verify consistency.

Trait Implementations

impl Clone for ContractKey

fn clone(&self) -> ContractKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractKey

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

Formats the value using the given formatter.

impl Deref for ContractKey

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &<ContractKey as Deref>::Target

Dereferences the value.

impl<'de> Deserialize<'de> for ContractKey

fn deserialize<__D>( __deserializer: __D, ) -> Result<ContractKey, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContractKey

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

Formats the value using the given formatter.

impl Hash for ContractKey

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ContractKey

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> TryFromFbs<&ContractKey<'a>> for ContractKey

fn try_decode_fbs(key: &ContractKey<'a>) -> Result<ContractKey, WsApiError>

impl Copy for ContractKey

impl Eq for ContractKey
