### `assertAccountDecoded()`
This function asserts that an account stores decoded data, ie not a Uint8Array. Note that it does not check the shape of the data matches the decoded type, only that it is not a Uint8Array.
```ts
type MyAccountData = { name: string; age: number };
const myAccount: Account<MyAccountData | Uint8Array, '1234..5678'>;
assertAccountDecoded(myAccount);
// now the account data can be used as MyAccountData
account.data satisfies MyAccountData;
```
This is particularly useful for narrowing the result of fetching a JSON parsed account.
```ts
const account: MaybeAccount<MockData | Uint8Array> = await fetchJsonParsedAccount<MockData>(
rpc,
'1234..5678' as Address,
)
assertAccountDecoded(account);
// now we have a MaybeAccount<MockData>
account satisfies MaybeAccount<MockData>
```
### `assertAccountsDecoded`
This function asserts that all input accounts store decoded data, ie not a Uint8Array. As with `assertAccountDecoded` it does not check the shape of the data matches the decoded type, only that it is not a Uint8Array.
```ts
type MyAccountData = { name: string; age: number };
const myAccounts: Account<MyAccountData | Uint8Array, Address>[];
assertAccountsDecoded(myAccounts);
// now the account data can be used as MyAccountData
for(const a of account) {
account.data satisfies MyAccountData;
}
```
