Struct Asset 

#[repr(C)]
pub struct Asset {
    pub id: AssetId,
    pub value: Word,
}

A fungible or non-fungible asset encoded as an asset id and a value word.

The id identifies the asset in a vault (issuing faucet, asset class, composition rule); value is the asset contents.

Fields

id: AssetId

The asset’s id, which identifies it in a vault.

value: Word

The asset’s contents.

Implementations

impl Asset

pub fn new(id: impl Into<AssetId>, value: impl Into<Word>) -> Self

Creates a new Asset from its id and value word.

pub fn id(&self) -> AssetId

Returns this asset’s id; the same value as the id field.

pub fn amount(&self) -> AssetAmount

Returns this asset’s fungible amount.

The composition rule is read from the asset id with AssetId::composition, which executes the protocol library’s asset::id_into_composition procedure.

Panics

Panics if the composition bits of the asset id hold an unrecognized value, if the asset is not fungible, or if its amount exceeds AssetAmount::MAX_U64.

pub fn is_fungible(&self) -> bool

Returns true if this asset is fungible.

The composition rule is read from the asset id with AssetId::composition, which executes the protocol library’s asset::id_into_composition procedure.

Panics

Panics if the composition bits of the asset id hold an unrecognized value.
