Enum AssetInfoBase

#[non_exhaustive]
pub enum AssetInfoBase<T: AddressLike> {
    Native(String),
    Cw20(T),
}

Represents the type of an fungible asset.

Each asset info instance can be one of three variants:

• Native SDK coins. To create an asset info instance of this type, provide the denomination.
• CW20 tokens. To create an asset info instance of this type, provide the contract address.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Native(String)

Cw20(T)

Implementations

impl<T: AddressLike> AssetInfoBase<T>

pub fn native<A: Into<String>>(denom: A) -> Self

Create an asset info instance of the native variant by providing the coin’s denomination.

use cw_asset::AssetInfo;

let info = AssetInfo::native("uusd");

pub fn cw20<A: Into<T>>(contract_addr: A) -> Self

Create an asset info instance of the CW20 variant

use cosmwasm_std::Addr;
use cw_asset::AssetInfo;

let info = AssetInfo::cw20(Addr::unchecked("token_addr"));

impl AssetInfoBase<Addr>

pub fn inner(&self) -> String

Return the denom or addr wrapped within AssetInfo

impl AssetInfoBase<String>

pub fn check( &self, api: &dyn Api, optional_whitelist: Option<&[&str]>, ) -> Result<AssetInfo, AssetError>

Validate data contained in an unchecked asset info instance; return a new checked asset info instance:

• For CW20 tokens, assert the contract address is valid;
• For SDK coins, assert that the denom is included in a given whitelist; skip if the whitelist is not provided.

use cosmwasm_std::{Addr, Api, StdResult};
use cw_asset::{AssetInfo, AssetInfoUnchecked};

fn validate_asset_info(api: &dyn Api, info_unchecked: &AssetInfoUnchecked) {
    match info_unchecked.check(api, Some(&["uatom", "uluna"])) {
        Ok(info) => println!("asset info is valid: {}", info.to_string()),
        Err(err) => println!("asset is invalid! reason: {}", err),
    }
}

impl AssetInfoBase<Addr>

pub fn query_balance<T: Into<String>>( &self, querier: &QuerierWrapper<'_>, address: T, ) -> Result<Uint128, AssetError>

Query an address’ balance of the asset

use cosmwasm_std::{Addr, Deps, Uint128};
use cw_asset::{AssetError, AssetInfo};

fn query_uusd_balance(deps: Deps, account_addr: &Addr) -> Result<Uint128, AssetError> {
    let info = AssetInfo::native("uusd");
    info.query_balance(&deps.querier, "account_addr")
}
