Implementations

impl AssetListUnchecked

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

Validate data contained in an unchecked asset list instance, return a new checked asset list 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::{Asset, AssetList, AssetListUnchecked, AssetUnchecked};

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