Struct Asset 

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

A fungible or non-fungible asset encoded as separate vault key and value words.

The key identifies the asset in the account vault and the value stores the corresponding asset contents. This matches the v0.14 protocol/base ABI.

Fields

key: Word

The asset’s vault key.

value: Word

The asset’s vault value.

Implementations

impl Asset

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

Creates a new Asset from its key and value words.

pub fn amount(&self) -> AssetAmount

Returns this asset’s fungible amount.

Intended for kernel-encoded assets (e.g. the ones returned by the get_assets bindings), whose encoding invariants make the composition bit sufficient to discriminate fungibility.

Panics

Panics if the asset is not fungible or its amount exceeds AssetAmount::MAX_U64.

pub fn is_fungible(&self) -> bool

Returns true if this asset is fungible.

Intended for kernel-encoded assets (e.g. the ones returned by the get_assets bindings), whose encoding invariants make the composition bit sufficient to discriminate fungibility.
