    ) -> StdResult<()> { ... }
}

A trait describing the interface of a Viewing Key store/vault.

It includes a default implementation that only requires specifying where in the storage the keys should be held.

Required Associated Constants

const STORAGE_KEY: &'static [u8]

Provided Methods

fn set_seed<S: Storage>(storage: &mut S, seed: &[u8])

Set the initial prng seed for the store

fn create<S: Storage>(
    storage: &mut S,
    env: &Env,
    account: &HumanAddr,
    entropy: &[u8]
) -> String

Create a new viewing key, save it to storage, and return it.

The random entropy should be provided from some external source, such as the user.

fn set<S: Storage>(storage: &mut S, account: &HumanAddr, viewing_key: &str)

Set a new viewing key based on a predetermined value.

fn check<S: ReadonlyStorage>(
    storage: &S,
    account: &HumanAddr,
    viewing_key: &str
) -> StdResult<()>

Check if a viewing key matches an account.
