Struct AssetVaultKey 

pub struct AssetVaultKey { /* private fields */ }

The unique identifier of an Asset in the AssetVault.

Its Word layout is:

[
  asset_id_suffix (64 bits),
  asset_id_prefix (64 bits),
  faucet_id_suffix (56 bits),
  faucet_id_prefix (64 bits)
]

See the Asset documentation for the differences between fungible and non-fungible assets.

Implementations

impl AssetVaultKey

pub fn new(asset_id: AssetId, faucet_id: AccountId) -> Result<Self, AssetError>

Creates an AssetVaultKey from its parts.

Errors

Returns an error if:

• the provided ID is not of type AccountType::FungibleFaucet or AccountType::NonFungibleFaucet
• the asset ID limbs are not zero when faucet_id is of type AccountType::FungibleFaucet.

pub fn to_word(self) -> Word

Returns the word representation of the vault key.

See the type-level documentation for details.

pub fn asset_id(&self) -> AssetId

Returns the AssetId of the vault key that distinguishes different assets issued by the same faucet.

pub fn faucet_id(&self) -> AccountId

Returns the AccountId of the faucet that issued the asset.

pub fn new_fungible(faucet_id: AccountId) -> Option<Self>

Constructs a fungible asset’s key from a faucet ID.

Returns None if the provided ID is not of type AccountType::FungibleFaucet

pub fn to_leaf_index(&self) -> LeafIndex<SMT_DEPTH>

Returns the leaf index of a vault key.

Trait Implementations

impl Clone for AssetVaultKey

fn clone(&self) -> AssetVaultKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssetVaultKey

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

Formats the value using the given formatter.

impl Display for AssetVaultKey

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

Formats the value using the given formatter.

impl From<Asset> for AssetVaultKey

fn from(asset: Asset) -> Self

Converts to this type from the input type.

impl From<AssetVaultKey> for Word

fn from(vault_key: AssetVaultKey) -> Self

Converts to this type from the input type.

impl From<FungibleAsset> for AssetVaultKey

fn from(fungible_asset: FungibleAsset) -> Self

Converts to this type from the input type.

impl From<NonFungibleAsset> for AssetVaultKey

fn from(non_fungible_asset: NonFungibleAsset) -> Self

impl Ord for AssetVaultKey

fn cmp(&self, other: &Self) -> Ordering

Implements comparison based on LexicographicWord.

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 AssetVaultKey

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

fn partial_cmp(&self, other: &Self) -> 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 TryFrom<Word> for AssetVaultKey

fn try_from(key: Word) -> Result<Self, Self::Error>

Attempts to convert the provided Word into an AssetVaultKey.

Errors

Returns an error if:

• the faucet ID in the key is invalid or not of a faucet type.
• the asset ID limbs are not zero when faucet_id is of type AccountType::FungibleFaucet.

type Error = AssetError

The type returned in the event of a conversion error.
