Implementations

impl MultiAsset

pub fn to_bytes(&self) -> Vec<u8>

impl MultiAsset

pub fn from_bytes(bytes: Vec<u8>) -> Result<MultiAsset, DeserializeError>

impl MultiAsset

pub fn to_hex(&self) -> String

impl MultiAsset

pub fn from_hex(hex_str: &str) -> Result<MultiAsset, DeserializeError>

impl MultiAsset

pub fn to_json(&self) -> Result<String, JsError>

pub fn from_json(json: &str) -> Result<MultiAsset, JsError>

impl MultiAsset

pub fn new() -> Self

pub fn len(&self) -> usize

the number of unique policy IDs in the multiasset

pub fn insert(&mut self, policy_id: &PolicyID, assets: &Assets) -> Option<Assets>

set (and replace if it exists) all assets with policy {policy_id} to a copy of {assets}

pub fn get(&self, policy_id: &PolicyID) -> Option<Assets>

all assets under {policy_id}, if any exist, or else None (undefined in JS)

pub fn set_asset(
    &mut self,
    policy_id: &PolicyID,
    asset_name: &AssetName,
    value: BigNum
) -> Option<BigNum>

sets the asset {asset_name} to {value} under policy {policy_id} returns the previous amount if it was set, or else None (undefined in JS)

pub fn get_asset(&self, policy_id: &PolicyID, asset_name: &AssetName) -> BigNum

returns the amount of asset {asset_name} under policy {policy_id} If such an asset does not exist, 0 is returned.

pub fn keys(&self) -> PolicyIDs

returns all policy IDs used by assets in this multiasset

pub fn sub(&self, rhs_ma: &MultiAsset) -> MultiAsset

removes an asset from the list if the result is 0 or less does not modify this object, instead the result is returned
