Returns

max_size, int64 - Maximum amount of delegatable resource shares. (Unit: sun)

• When querying the delegatable Energy share of an account, if the available Energy share in the account is 0, this API returns {}
• When querying the delegatable Bandwidth share of an account, if the Bandwidth obtained by staking in the account is not enough to pay for the Bandwidth consumed by a resource delegation transaction itself, this API also returns {}

Note:

If the delegating transaction has a memo, it would consume more Bandwidth, therefore the actual delegatable share would be less than the return of this API.
