Creates a new instance of double storage key from the array.

pub fn from_slice(slice: &[u8]) -> Result<ContractsAssetKey, TryFromSliceError>

Creates a new instance of double storage key from the slice.

pub fn contract_id(&self) -> &ContractId

Returns the reference to the first sub-key.

pub fn asset_id(&self) -> &AssetId

Returns the reference to the second sub-key.

Trait Implementations

impl AsRef<[u8]> for ContractsAssetKey

impl Clone for ContractsAssetKey

fn clone(&self) -> ContractsAssetKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContractsAssetKey

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

Formats the value using the given formatter.

impl Default for ContractsAssetKey

fn default() -> ContractsAssetKey

Returns the “default value” for a type.

impl<'a> Deserialize<'a> for ContractsAssetKey

fn deserialize<D>( deserializer: D, ) -> Result<ContractsAssetKey, <D as Deserializer<'a>>::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl From<(&ContractId, &AssetId)> for ContractsAssetKey

fn from(pair: (&ContractId, &AssetId)) -> ContractsAssetKey

Converts to this type from the input type.

impl From<ContractsAssetKey> for [u8; 64]

fn from(key: ContractsAssetKey) -> [u8; 64]

Converts to this type from the input type.

impl Hash for ContractsAssetKey

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 Ord for ContractsAssetKey

fn cmp(&self, other: &ContractsAssetKey) -> 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 ContractsAssetKey

fn eq(&self, other: &ContractsAssetKey) -> 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 ContractsAssetKey

fn partial_cmp(&self, other: &ContractsAssetKey) -> 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 Serialize for ContractsAssetKey

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 TryFrom<&[u8]> for ContractsAssetKey

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from( slice: &[u8], ) -> Result<ContractsAssetKey, <ContractsAssetKey as TryFrom<&[u8]>>::Error>

Performs the conversion.
