Account information for use by snapp smart contracts.

Fields

app_state: [Fp; 8]

General purpose storage for use by the snapp associated with this account.

verification_key: Option<VerificationKey>

Verification key for the snapp associated with this account, or None if this account has no associated snapp.

snapp_protocol_version: u32

Snapp protocol version

sequence_state: SequenceState

History of sequenced event updates for the most recent 5 slots with updates

proved_state: bool

true if the current app_state was initialized by a transaction authorized using a proof, and every subsequent update was also authorized by a transaction using a proof; false otherwise.

Snapp authors may use this field to validate that their snapp was initialized honestly and correctly before being used.

uri: &'a str

URI to access the code and other resources for this account’s snapp smart contract

token_symbol: &'a str

The symbol for the token managed by this account. This string has a maximum length of 6 characters.

Implementations

impl<'a> SnappAccount<'a>

pub fn empty() -> SnappAccount<'a>

The ‘empty’ snapp account state. The snapp field of an account is equivalent to this value if and only if it is set to None.

empty() =
SnappAccount {
    app_state: [Fp::zero(); 8],
    verification_key: None,
    snapp_protocol_version: 0,
    sequence_state: SequenceState::empty(),
    proved_state: false,
    uri: "",
    token_symbol: "",
}

pub fn is_empty(snapp: &SnappAccount<'a>) -> bool

Returns true if the argument is identical to SnappAccount::empty, false otherwise.
