Struct miden_objects::assets::NonFungibleAsset

pub struct NonFungibleAsset(/* private fields */);

A commitment to a non-fungible asset.

The commitment is constructed as follows:

• Hash the asset data producing [d0, d1, d2, d3].
• Replace the value of d1 with the fauce id producing [d0, faucet_id, d2, d3].
• Force the bit position ACCOUNT_ISFAUCET_MASK of d3 to be 0.

NonFungibleAsset itself does not contain the actual asset data. The container for this data NonFungibleAssetDetails struct.

Implementations

impl NonFungibleAsset

pub fn new(details: &NonFungibleAssetDetails) -> Result<Self, AssetError>

Returns a non-fungible asset created from the specified asset details.

Errors

Returns an error if the provided faucet ID is not for a non-fungible asset faucet.

pub fn from_parts( faucet_id: AccountId, data_hash: Word ) -> Result<Self, AssetError>

Return a non-fungible asset created from the specified faucet and using the provided hash of the asset’s data.

Hash of the asset’s data is expected to be computed from the binary representation of the asset’s data.

Errors

Returns an error if the provided faucet ID is not for a non-fungible asset faucet.

pub unsafe fn new_unchecked(value: Word) -> NonFungibleAsset

Creates a new NonFungibleAsset without checking its validity.

Safety

This function required that the provided value is a valid word representation of a NonFungibleAsset.

pub fn vault_key(&self) -> Word

pub fn faucet_id(&self) -> AccountId

Return ID of the faucet which issued this asset.

Trait Implementations

impl Clone for NonFungibleAsset

fn clone(&self) -> NonFungibleAsset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonFungibleAsset

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

Formats the value using the given formatter.

impl Display for NonFungibleAsset

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

Formats the value using the given formatter.

impl From<NonFungibleAsset> for Word

fn from(asset: NonFungibleAsset) -> Self

Converts to this type from the input type.

impl From<NonFungibleAsset> for [u8; 32]

fn from(asset: NonFungibleAsset) -> Self

Converts to this type from the input type.

impl From<NonFungibleAsset> for Asset

fn from(asset: NonFungibleAsset) -> Self

Converts to this type from the input type.

impl PartialEq for NonFungibleAsset

fn eq(&self, other: &NonFungibleAsset) -> 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 TryFrom<[BaseElement; 4]> for NonFungibleAsset

type Error = AssetError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<[u8; 32]> for NonFungibleAsset

type Error = AssetError

The type returned in the event of a conversion error.

fn try_from(value: [u8; 32]) -> Result<Self, Self::Error>

Performs the conversion.
