获取 storaged u64 上的默认值
Get default value on storaged u64
我想获取存储值,如果不存在,请给我0
const lastDeposit = storage.get<u64>('lastDeposit', u64(0)) || u64(0);
但是编译器抛出
ERROR AS204: Type 'u64' cannot be nullable.
static get<T>(key: string, defaultValue: T | null = null): T | null {

你必须以 lastDeposit
永远不允许 null
的方式来表达
这是为我编译的,但有错误
const lastDeposit: u64 = storage.getSome<u64>('lastDeposit') || 0;
