Struct AssetId

pub struct AssetId { /* private fields */ }

CAIP-19 Asset ID implementation

An Asset ID is a string that identifies a blockchain asset and follows the format: <chainId>/<assetNamespace>:<assetReference>

• chainId: CAIP-2 Chain ID (e.g., “eip155:1” for Ethereum mainnet)
• assetNamespace: Protocol or standard (e.g., “erc20”)
• assetReference: Asset-specific identifier (e.g., token contract address)

Example: “eip155:1/erc20:0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48” for USDC on Ethereum

Implementations

impl AssetId

pub fn new( chain_id: ChainId, namespace: &str, reference: &str, ) -> Result<Self, Error>

Create a new AssetId from ChainId, asset namespace, and reference

Arguments

• chain_id - The CAIP-2 Chain ID
• namespace - The asset namespace (e.g., “erc20”)
• reference - The asset reference (e.g., token contract address)

Returns

• Result<AssetId, Error> - An AssetId or an error if validation fails

pub fn chain_id(&self) -> &ChainId

Get the chain ID component

pub fn namespace(&self) -> &str

Get the asset namespace component

pub fn reference(&self) -> &str

Get the asset reference component

Trait Implementations

impl Clone for AssetId

fn clone(&self) -> AssetId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssetId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssetId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AssetId

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

Formats the value using the given formatter.

impl FromStr for AssetId

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a string into an AssetId

Arguments

• s - A string in the format “namespace:reference/assetNamespace:assetReference”

Returns

• Result<AssetId, Error> - An AssetId or an error if parsing fails

type Err = Error

The associated error which can be returned from parsing.

impl Hash for AssetId

fn hash<__H: Hasher>(&self, state: &mut __H)

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 PartialEq for AssetId

fn eq(&self, other: &AssetId) -> 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 Serialize for AssetId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
